I just swapped out my 416's for vortex 906 on my 350 went through 3 pairs of cracked ones but finally got a good set, running .510 lift I was shocked by the power difference
Thanks for the info, I have built small and big block Mopar for years, now retired I am starting to do Chev. also you are a big help. I am only 35 min. from Summit and 3 Hrs. from Jegs so I have a good pool to pick from.
Awesome vid man.. I'm rebuildin my 99 LT Sport 2 dr, front susp timing, cooling sys exp plugs mounts, and maybe a new trans... About half way there, exactly what I needed to hear to see it all through! Thanks! ; )
Took my 062 Vortec Heads to the Head Doctor (Machine Shop) yesterday for a MagnaFlux and Decking....Got a good Bill of Health No cracks and everything looks great. $35.00 each head Magnaflux, $55.00 each for decking...$180.00 total...I'm happy ! Now I gotta talk myself into trying to fit these heads and new manifold into my old Cube Van thru the DogHouse !
Jeep fans have a similar situation. The 331 4.0L head casting is crack prone. Clearwater Cylinder Head and Alabama Cylinder heads build a new heavier casting that is unlikely to crack. You can use those heads as a performance upgrade as well. The 4.2L Jeep engine gets a huge power boost by installing the 331 replacement head.
I port matched my 906 heads and Edelbrock intake performer RPM intake installed an LT4 hot cam from GM Performance and blue beehive springs and only cost me a few hundred bucks and GOD DAMN did it ever make a difference on power, it went from a tire smoker to a tire destroyer and massively improved high end power on the highway, I love Vortecs, cheap, make great power easily without spending a lot of money and easy to work on
I was lucky enough to get a set of the pro topline Australian vortec heads from an engineer at comp cams in 2002. He hooked me up with, at the time, unreleased to the public beehive springs, retainers and Manley valves. In a 5200 lb truck, that engine pushed it to 13.0’s and at redline with a 1:1 trans and 3:73 gears it would hit 140 mph with the right da.
Great video. I was going to buy a set of aftermarket Vortec heads from Scoggy Dickey for my 79 350 but the tech said I had to drill one hole in the passenger side heads for the water pump by pass. I know the sb 400's needs the steam holes drilled. Thanks

+Myvintageiron7512 I am doing a rebuild on a 350. I got a set of heads, 041 castings from a machine shop. They did a full valve job, hardened seats, 2.02 swirl polished intake valves new stainless 1.60 swirl polished exhaust valves new .500 Z-28 lift valve springs. I also picked up a set of Vortec 906 castings from Facebook Marketplace. I have inspected them, don't see any cracks - will have this verified. My question is this: Ever considering that the 041 castings are like new and rebuilt and the 906 heads are not - would I get more power from the Vortec heads?
vortec heads are modern tech applied to your classic chevy compatibility. when your block has been in production for 50 years, last year's heads had 10 years more advanced than last decade's heads. i think its pretty obvious that the new stuff is better than old bc its got all the old stuff to learn from
Vintageiron- thanks for the informative videos!! they are awesome and hope to see more as time allows. i have a 1968 C-10 with a goodwrench 350. i plan on adding some punch to it, nothing crazy. in your opinion, how would an RV cam, vortec heads, RPM air gap intake, edelbrock 1406, truck headers and purple hornies turned down before the diff perform? this is a learning experience and my 1st build. also, right now it has a TH400 and i believe 4.11 gears now but plan on converting to a 700R4 and 3.42 gears with the eaton truetrac... hope to hear from ya soon and thanks again!
Put in a colder thermostat 180 and replace all of the quick release coolant fittings with new ones. Do the bottle cap too. Keep water in it and it will be a good engine. Just very well known for small coolant leaks.
yeah i had the same problem. im a vw guy and i bout like 3 sets of dual port heads for 50 bucks! heck yeah now all i have to do is get them cut for 94s and maybe they wont need rebuilt.... nope needed rebuilt and the shop pretty much told me. dont waste your time. spend the money on new heads... your building an engine. spend the money. dont waste time hoping old parts will clean up and be good and maybe save you at most $200 bucks in the whole build. $200 dollars is a big whoop when the old part cracks and ruins the $2,000 dollar motor.
HI MVI...So at the 10:20 mark you said that I can just bolt on a set of Vortec heads (602s) right to my stock 1982 350 van engine without installing a Roller Cam or different pistons and I should get a 30/40 hp gain ? Thanks Brother... I love your videos ! I'm gonna get your suggested Manifold Gasket too ! Oh yeah.... What Head bolts and Head gaskets do I use...my Vortec heads are 602s out of a 98 pickup truck going into my stock 1982 Chevy 350 Cube Van.
get a new set of head bolts, OEM is fine, intake gaskets are fel pro (MS 98000 T) these intake gaskets are an absolute must for this swap I think you ment 062 castings not 602 but I get it, yes you can do a direct swap with flat tappet cam asuming the flat tappet you are running is stock lift
@@Myvintageiron7512 Thanks MVI Yes I meant 062 Vortec heads, they are being Magnafluxed and Decked as we speak ! Needed to know what Head Gaskets to use ! I Really appreciate your reply !
Best bang for your buck up here is getting some Iron Eagles. By the time you rebuild a pair of Vortecs your only a couple hundred off of buying new Darts. Ported vortecs flow a little less than as cast iron eagles
I never knew vortec heads were that good I may get a set of vortec aluminum heads on rockauto because I would like to wake up my 350 tbi motor lol would it work if I kept the tbi throttle body and put on bigger injectors?
What company do you recommend for the aftermarket heads. I know this video was made a few years back but I'm having trouble finding exactly what I need
@@Myvintageiron7512 hello, been watching your videos for a while and love that your showing us younger generation the tools and knowledge that we need and not like others with misinforming info. is Dart the only brand you would buy vortec's from? of me not knowing iv always wondered about afr and eldelbrock e tech heads along with dart and others. like everyone else including you before you decided not to anymore, i was really thinking about going to the junk yard and pulling set after set to find ones not cracked but i would like to make a good investment that i know wont crack. Thankyou very much for your time -Patrick
Sergeant Speed i got 475 from a 4.3 vortec which has 185 hp stock. Not getting into a long winded explanation of all the work/parts and the specs of ech mod. think about a old school 350 making 1000 hp. Its not hard when you have the money or/and the time to do the work yourself.
@@bonnivilleblackcherry9745 he said he has 400 hp with a sbc using vortec heads. I wanted to see what he was using for parts to make 140 horsepower over stock with heads that only boost power by 30ish horsepower I know you can make decent power from a SBC, That wasn't my question.
So I was told that if you port the intake runners on a vortec head, it looses its "Vortec" property of swirling the air fuel charge as it goes into the cylinder. If I remember correctly, the 2016 chevy performance parts catalog said that too. Are they just telling me that so I buy the bowtie heads with the 225CC intake runners or is it possible to port a vortec head runner to say 190cc or 200cc? Thoughts?
I enjoy your videos. There are some other master mechanics that say that it is not a good idea to bolt on aftermarket heads right out of the box because they have improper machine work and other issues. What is your take on that?I want to buy some aftermarket heads ready to bolt on but after seeing different videos I am not sure.Again thank you for your videos.
It depends on where the heads came from if you buy cheap aftermarket heads from overseas than I agree 100% the valve job's are atrocious, however if you buy Dart, AFR, or Trick Flow, I do not agree they have top notch machine work done by CNC machines that is hard to match with manual machine work
buy new al heads 906 are ok at best listen to his video all that 906 ant but 200cc bare finish ot home shop or local never buy any pre assembled @@nickblais4371
I would like to know about the 191 heads.i bought a set with 202 stainless valves and ported and polished.did I screw up or will they work with a 510 lift cam?!
I’ve been told that you can punch a hole in the vortec head to accommodate an egr so you can still use the old intake, with a lot of grinding. Can you please comment on that?
+Myvintageiron7512 are the aftermarket Vortec style heads better than a set of 041 casting camel humps that have been ported, polished, and have swirl 2.02/1.60? I bought a reconditioned set of these camel humps before I found the Vortecs. I have about 800 in the camel humps. Love your channel and content!
@@Myvintageiron7512 Like enough to buy some aftermarket ones and sell my camel hump better...or not that much of a difference to take the loss? - also thanks for getting back to me! AWESOME CHANNEL!
when you pointed out the exhaust seat cracks i noticed cracks in the one center hold down bolt hole. what do you think of those cracks? i have a set with cracks there, otherwise good heads. do you think that location would cause much trouble?
I do have several small block builds that show the head install they are all pretty much the same TBI is no different that the earlier heads as far as install goes
your videos are very informative I am considering building a 383 with vortec heads what combination would be great for cam I want to use it as a daily driver but still be in the 400 to 500 horsepower band if possible
I am very interested in putting vortec heads on my TBI 350. Ive watched all of your vids on this subject. if you see this would you please let me talk to you in more detail?
The vortec head is based on iron lt1 350 head. Nothing to do with tbi head although you would think the swirl port heads that actually create a real vortex would have carried the vortec name
Are the new crate vortec long blocks coming with the same castings? About to pull the trigger on one. Pretty sure I should have no problems for a long time anyways. Thanks
What are the specs on the cam ? I am building a Vortec engine for my '87 Chevy P/U. It is going to be a stroker. I watched your videos and learned a few things. I have built a couple stroker engines but it was a long time ago, '95 was the last one. I am a retired auto mechanic and now it is an expensive hobby that I enjoy very much. I work out of town a lot so I don't have much time to work on my babies. I really enjoy your videos. Thank You.
what pistons did you use on the vortex I bought a new gm vortex 350 crate engine for my truck I put a bigger cam in it did not go to high on the lift do to the clearance issues installed a set of bbk headers and cold air intake it is so much more enjoyable to drive good power better gas mileage kind of a project with my son teaching him engine work and it's fun looking for more power wondering about pistons
how well do your vortec head mods work? I have 3 pairs of 062 heads that are in great shape. I do not want to go over board with the porting. I am mostly interested in smoothing out the exhaust side and getting rid of that ridge line in the throat just under the seat, approximately 3/4" under the seat. That spot in the throat has a rough unfinished ridge that seems to "choke" the exhaust a bit. Anyway, the other place I want to work is the CHAMBER! I notice the spark-plug BOSS having the sharp corners. That spark-plug boss looks like it would interfere with the flow and hot spots. What and how and why do you work the combustion chamber for the vortec??? I want to do an improvement for a 450 HP goal. what are your flow numbers after the chamber improvement and exhaust cleanup? Is just removing the spark plug boss in the vortec going to improve flow any? or even change any characteristics of performance? if so, what kind? keep up the vortec vids, the vortec is an amazing head that everyone seems too scared to venture too far into, and I want to see someone who are diehard vortec builders that figured out a good recipe for good flow in those heads.
Hi Mate. Thanks for all the info Can you recommomend direct replacement aftermarket heads for our 305 Vortec marine motor? Heads are 906, have been quoted replacment parts will be 3 valves and 3 seats (2 Exh 1 Int) on one head, as the heat transfer in the exhaust manifold was leaking and let salt water into # 3,5 cylinders. Have been quoted around $1200 to re condition and fix both existing heads.
skoggins and dickie or any gm performance should have stock 305 vortec heads orderable much cheaper,also check summit performance and jegs,as a side note you can also use 350 vortec heads but they must have the deck milled down to reduce the combustion chamber to a 305 size.
Craig mac, 062 and 906 heads are 350 vortec heads. The 059 were vortec 305 heads like he was asking about. 059 heads had a smaller combustion chamber (like 58 or 59cc IIRC).
Great videos! Can you drill/adapt the vortec heads to bolt on an old style intake manifold? I have an 82 corvette with the crossfire. My plan was to get the renegade intake and a nice set of heads. Possibly port out the throttle bodies also. Or do you think a performance style aluminum head would just be more cost effective?
Can you suggest a cam for a truck I use for plowing that I don't have to have the valve bosses cut? I have the heads bolted down and don't want to take them apart to send them to the machine shop. I'm using a 750 vac. secondary carb. It will be a flat tappet setup too.
I have a `91 Silverado....tbi swirl port heads...NO BALLS at all....can you do a video on swapping out the garbage and adding the vortec goodness...I saw the Engine masters episode too..will use aftermarket heads..lit the fire in me for the swap. thx..keep up the vids!!! My engine was a rebuilt 350 5 years ago.
It's actually pretty easy you do the same thing all you need is an intake edelbrock makes one that takes your throttle body instead of a carb other than that it's all about the same as the video you will need to have it tuned if you go with a bigger cam but any dyno tune shop can do it pretty easily
Steven Zdziebkowski I have a source that sells stock replacement Vortec heads they will work on a marine engine the heads were not much different it is the short block that was quite different they are $ 700 a set finding good factory castings is nearly impossible to find
I'm considering getting Vortec heads for an old 305 of mine from 1992, I had read that the intake manifold bolt pattern and angles are different and thus require a dedicated Vortec fuel induction system. Could I slap a '91-'92 era TPI intake manifold on the Vortec heads and it work just fine, since in '87 they already switched the bolt pattern/angles on their stock intake manifolds and heads? I'm trying to build for lower end torque from this 305 as well, so whatever aftermarket or stock multi port fuel injection system worked best for a 305 throughout the power curve to 5000 RPM would be great info too, I'm afraid I might be searching in vain. Thanks in advance.
A factory TPI manifold and Vortec heads have different bolt patterns, the Vortecs use 4 vertical bolts rather than 6 angled bolts like gen 1 small block heads. That being said I believe there are aftermarket TPI base manifolds designed for Vortec heads. Also, always remember that a Vortec head has a different port than a gen 1 sbc head, it's taller and more narrow. The factory TPI intake wouldn't be a perfect match anyway. Sorry bud!
Yep, I did some few bit of research, the term Vortec came out around '86, but true Vortec didn't come out until '96. There's some differences in Vortec blocks as well, but it's negligible. Scoggin Dickey is making a factory style stock Vortec TPI intake manifold, and pretty much any company that makes aftermarket intakes also make Vortec style, the Scoggin Dickey model is going to be the one that requires the least amount of modifications and tuning to get right. The real question is what are the differences between 520 and 059 factory cast 305 Vortec heads, I've seen valve sizes vary between 1.84" and 1.94", and runner lengths going all over the place on forums.
I could be wrong, but I've heard the Vortec 305's used a TBI style, "swirl port" head. I'm not familiar with them, vintage iron would be the guy to ask, hopefully he weighs in here...
The 059's I've heard have swirl port, while the 520's don't. I've also read on a casting number sheet for both blocks and heads that 1997 305's were the only year for 059 castings, all later Vortec 305 heads were 520s.
Sounds like you're on the right track, I have no experience with Vortec 305's so you could fool me. Hopefully you find the castings you are after, good luck!
Hey I like your vids, Being an OLD chevy guy I find you very informative. I am a multi ticketed mechanic and worked from light engines to truck and coach and heavy equipment. My field was to diagnose problems and just to keep the stuff running. Getting the most performance from my cars was just a hobby and in those days no internet. Now you can call male bovine poo on this " a crack in the head does not automatically mean junk".Cummins denied warranty on cracks from valve seat insert to the injector unless there was either compression leakage or coolant leakage. Another example, Pontiac Quad4 engines white froth around the dip stick, heads would get pulled and cracks from valve seat to spark plug hole were found. Head is condemned, they all craced there and NO coolant leak. What engineer decided to put the crankcase vent on the dip stick tube DUH. Then unscrupulous mechanics would capitalize on mechanically challenged customers with unneeded repairs. Anyways a monkeys but doesn't have a crack does it work any better?
I have an 85 corvette with 85,000 miles and a L98 dog. Would like to install vortec heads with a better cam. My problem is I would like to keep my TPI setup. I saw a intake from SD parts that would accomplish this but I says on their website no longer available. Any ideas? Really appreciate all the valuable info on your channel very helpful.
MVI, Talkin about Vortex heads. I have twin MPI Mercruiser 350 block engines stroked to 377@ 320 hp. I want to go with aluminum Vortex heads to shed weight and better flow. A marine Comp Cam also installed. BUT I would like to use the stock 2 piece intake and throttle body because of simplicity. I would also have to have the ECU's remapped. AM I LOOKINH AT THIS ALL WRONG?
i am getting back into the engine building business. your info has been great . whats valve diameter on these? and are they comparable to the old turbo heads street wise? or can they be modified to do so?
I was looking to do a budget build for my 79 K10 pickup. It's got the original (as far as I know) 350 in it. My machine shop has a pretty reasonable package on a rebuild of that core. But I was wondering about going to a hydraulic roller engine. I had thought about doing the L31 but there are no provisions for a mechanical fuel pump in there and I don't really want to go electric due to simplicity reasons. I was wanting to know what your thoughts were on a hydraulic roller block that will use old style or Vortec style heads and have provisions for a mechanical fuel pump. Maybe a TBI block with Vortec heads? I've seen some sources claim those blocks supported mechanical fuel pumps. I know the ZZ4 crate block would work out nicely but It's more money than I want to spend for what this build is intended for.I don't mind paying the money for the aftermarket vortec style heads. Just wonderinf if the juice is worth the squeeze or I should just go with the OE style flat tappat setup.
I promise to stop bothering you after this one ...I have a set of 062 Vortec heads going on a stock 1982 Chevy 350 engine... you said get a set of OEM Head Bolts...are they Stock Head Bolts for the 1982 Chevy engine or for the 1998 062 Chevy Vortec Heads (if there is a difference) and what Head Gasket would you suggest...it's all mainly stock except the Vortec heads. I have already ordered the MS 98000 T Intake manifold Gasket you suggested for Vortec Heads ! Thanks again...You Rock Brother !
You have options to port deoending on what intake you are using, you can use the felpro 2205 or 2206, or the felpro raised runner gaskets. You will have to port to the gasket you are using. After you port match the opening, you are still limited to the smallest part of the runner. But you will flow better by port matching vs. not.
hey myvintageiron, Have you ever used ProComp heads on a SBC build? I know they are China heads and the assembled ones are put together with junk parts, but i think that if I were to buy them bare, then rebuild them with all new everything they would be ok for around 525 horse. What do you think?

yeah i had the same problem. im a vw guy and i bout like 3 sets of dual port heads for 50 bucks! heck yeah now all i have to do is get them cut for 94s and maybe they wont need rebuilt.... nope needed rebuilt and the shop pretty much told me. dont waste your time. spend the money on new heads... your building an engine. spend the money. dont waste time hoping old parts will clean up and be good and maybe save you at most $200 bucks in the whole build. $200 dollars is a big whoop when the old part cracks and ruins the $2,000 dollar motor.
HI MVI...So at the 10:20 mark you said that I can just bolt on a set of Vortec heads (602s) right to my stock 1982 350 van engine without installing a Roller Cam or different pistons and I should get a 30/40 hp gain ? Thanks Brother...
I love your videos ! I'm gonna get your suggested Manifold Gasket too ! Oh yeah.... What Head bolts and Head gaskets do I use...my Vortec heads are 602s out of a 98 pickup truck going into my stock 1982 Chevy 350 Cube Van.
get a new set of head bolts, OEM is fine, intake gaskets are fel pro (MS 98000 T) these intake gaskets are an absolute must for this swap I think you ment 062 castings not 602 but I get it,
yes you can do a direct swap with flat tappet cam asuming the flat tappet you are running is stock lift
@@Myvintageiron7512 Thanks MVI Yes I meant 062 Vortec heads, they are being Magnafluxed and Decked as we speak ! Needed to know what Head Gaskets to use !
I Really appreciate your reply !
How about the engine quest brand heads? How about the engine quest hybrid head? They have the vortec chamber but the tbi intake bolt pattern.
yea they are ok
please give the manufacturer and part number for the aftermarket vortec heads

When you speak of the TPI engine heads are those the L98 heads?
SO MUCH great info from this channel
What is your opinion on the early bowtie heads casting 14011034, thanks.
Decnt heads
so i can buy a aftermarket vortec heads and bolt them to my TBI 350 with no issues?
Issue is manifold
Where can i order those aftermarket vortec heads? im from Canada? and is there a certain casting number im looking for?
Best bang for your buck up here is getting some Iron Eagles. By the time you rebuild a pair of Vortecs your only a couple hundred off of buying new Darts.
Ported vortecs flow a little less than as cast iron eagles
summit sells vortec heads and a couple aftermarket variants,check jegs as well
were did you get the after market vortec?

I never knew vortec heads were that good I may get a set of vortec aluminum heads on rockauto because I would like to wake up my 350 tbi motor lol would it work if I kept the tbi throttle body and put on bigger injectors?
What company do you recommend for the aftermarket heads. I know this video was made a few years back but I'm having trouble finding exactly what I need
Dart
@@Myvintageiron7512 hello, been watching your videos for a while and love that your showing us younger generation the tools and knowledge that we need and not like others with misinforming info. is Dart the only brand you would buy vortec's from? of me not knowing iv always wondered about afr and eldelbrock e tech heads along with dart and others. like everyone else including you before you decided not to anymore, i was really thinking about going to the junk yard and pulling set after set to find ones not cracked but i would like to make a good investment that i know wont crack. Thankyou very much for your time -Patrick
I got a GMC Yukon 1997 and it has the good vortex heads its running 400hp
tia sprague would love to know how you got 400 hp from a 260 hp motor
vorteC not vorteX.
Sergeant Speed i got 475 from a 4.3 vortec which has 185 hp stock.
Not getting into a long winded explanation of all the work/parts and the specs of ech mod. think about a old school 350 making 1000 hp. Its not hard when you have the money or/and the time to do the work yourself.
@@bonnivilleblackcherry9745 he said he has 400 hp with a sbc using vortec heads. I wanted to see what he was using for parts to make 140 horsepower over stock with heads that only boost power by 30ish horsepower
I know you can make decent power from a SBC, That wasn't my question.
ok tq may be
What's the piston and cam model numbers you changed in the up grades in that engine
Can you talk about the head swap from tbi to Vortec
take tbi heads off,throw them out.put vortec heads on
Do all factory vortecs have the tripple hump pattern. Been junkyard diving and a Lot of the the 96-2000 5.7s don't. Not confusing vortec with tbi.
no they don't all have that
So I was told that if you port the intake runners on a vortec head, it looses its "Vortec" property of swirling the air fuel charge as it goes into the cylinder. If I remember correctly, the 2016 chevy performance parts catalog said that too. Are they just telling me that so I buy the bowtie heads with the 225CC intake runners or is it possible to port a vortec head runner to say 190cc or 200cc? Thoughts?
I enjoy your videos. There are some other master mechanics that say that it is not a good idea to bolt on aftermarket heads right out of the box because they have improper machine work and other issues. What is your take on that?I want to buy some aftermarket heads ready to bolt on but after seeing different videos I am not sure.Again thank you for your videos.
It depends on where the heads came from if you buy cheap aftermarket heads from overseas than I agree 100% the valve job's are atrocious, however if you buy Dart, AFR, or Trick Flow, I do not agree they have top notch machine work done by CNC machines that is hard to match with manual machine work
I need to know if filling the center 2 intake bolt holes or am I gonna need a new tbi intake for Vortec heads
Awesome thanks for the information on the LS engine and cast iron engines
what company makes a good aftermarket vortec head and manifold
New videos! yes! Make one on the Chevy 400 please
Yes please do a 400sbc. I'm building one now with vortec 906 heads, steam ported, and a comp cam 268/268 at .454 /.454. I could use the advice.
buy new al heads 906 are ok at best listen to his video all that 906 ant but 200cc bare finish ot home shop or local never buy any pre assembled @@nickblais4371
@@nickblais4371 Get aftermarket shorty valve seals and press them on all the way. You will get way more clearance so you can run a .480" lift cam.
I would like to know about the 191 heads.i bought a set with 202 stainless valves and ported and polished.did I screw up or will they work with a 510 lift cam?!
should work fine make sure the valve springs match the cam
Myvintageiron7512 any idea what cc the 191 is
Are you finding a specific casting number that’s cracking with the vortec heads? 906 or 062. Or are they both prone to cracking?
Both
I’ve been told that you can punch a hole in the vortec head to accommodate an egr so you can still use the old intake, with a lot of grinding. Can you please comment on that?
+Myvintageiron7512 are the aftermarket Vortec style heads better than a set of 041 casting camel humps that have been ported, polished, and have swirl 2.02/1.60? I bought a reconditioned set of these camel humps before I found the Vortecs. I have about 800 in the camel humps. Love your channel and content!
vortec's are better

You got any advice of taking stock vortec heads and taking down the valve bumpers so you can get more lift ?
ruclips.net/user/edit?o=U&video_id=wYtAY6QqE9Y
when you pointed out the exhaust seat cracks i noticed cracks in the one center hold down bolt hole. what do you think of those cracks? i have a set with cracks there, otherwise good heads. do you think that location would cause much trouble?
takethepills i wouldn't use them, you could leak coolant into oil
I got a few questions. Do they have 202 valves and can you put any carb intake on them?
you don't want 2.020 valves in Vortec heads the chambers are to small and they shroud the valves which kills air flow
Max Piston to Cylinder Bore Clearance allowed can you do a video for that for a 383, 350., 400 sbc
Do you have a video on putting these heads on a tbi 350? specifically a 1992 truck motor.
or is there a similar head that will fit a tbi and give me the same power increase? Thanks for any advice!!
I do have several small block builds that show the head install they are all pretty much the same TBI is no different that the earlier heads as far as install goes
Dude! thanks for answering, and quickly i might add. Subbed!
your videos are very informative I am considering building a 383 with vortec heads what combination would be great for cam I want to use it as a daily driver but still be in the 400 to 500 horsepower band if possible
I am very interested in putting vortec heads on my TBI 350. Ive watched all of your vids on this subject. if you see this would you please let me talk to you in more detail?
buy vortec heads,used from 1996 to 1998 or buy aftermarket vortec heads from summit
The vortec head is based on iron lt1 350 head. Nothing to do with tbi head although you would think the swirl port heads that actually create a real vortex would have carried the vortec name
Are the new crate vortec long blocks coming with the same castings? About to pull the trigger on one. Pretty sure I should have no problems for a long time anyways. Thanks
What are the specs on the cam ? I am building a Vortec engine for my '87 Chevy P/U. It is going to be a stroker. I watched your videos and learned a few things. I have built a couple stroker engines but it was a long time ago, '95 was the last one. I am a retired auto mechanic and now it is an expensive hobby that I enjoy very much. I work out of town a lot so I don't have much time to work on my babies. I really enjoy your videos. Thank You.
what pistons did you use on the vortex I bought a new gm vortex 350 crate engine for my truck I put a bigger cam in it did not go to high on the lift do to the clearance issues installed a set of bbk headers and cold air intake it is so much more enjoyable to drive good power better gas mileage kind of a project with my son teaching him engine work and it's fun looking for more power wondering about pistons
how well do your vortec head mods work? I have 3 pairs of 062 heads that are in great shape. I do not want to go over board with the porting. I am mostly interested in smoothing out the exhaust side and getting rid of that ridge line in the throat just under the seat, approximately 3/4" under the seat. That spot in the throat has a rough unfinished ridge that seems to "choke" the exhaust a bit. Anyway, the other place I want to work is the CHAMBER! I notice the spark-plug BOSS having the sharp corners. That spark-plug boss looks like it would interfere with the flow and hot spots. What and how and why do you work the combustion chamber for the vortec??? I want to do an improvement for a 450 HP goal. what are your flow numbers after the chamber improvement and exhaust cleanup? Is just removing the spark plug boss in the vortec going to improve flow any? or even change any characteristics of performance? if so, what kind? keep up the vortec vids, the vortec is an amazing head that everyone seems too scared to venture too far into, and I want to see someone who are diehard vortec builders that figured out a good recipe for good flow in those heads.
Got a question I have camel humps on a motor my dad built b4 he passed if I switch to vortec heads would I have to change the headers?
no

+Tony Wilkins Hmm alright. Just wondering what a good engine would be for me to get into engine building without breaking the bank
Hi Mate.
Thanks for all the info
Can you recommomend direct replacement aftermarket heads for our 305 Vortec marine motor?
Heads are 906, have been quoted replacment parts will be 3 valves and 3 seats (2 Exh 1 Int) on one head, as the heat transfer in the exhaust manifold was leaking and let salt water into # 3,5 cylinders. Have been quoted around $1200 to re condition and fix both existing heads.
skoggins and dickie or any gm performance should have stock 305 vortec heads orderable much cheaper,also check summit performance and jegs,as a side note you can also use 350 vortec heads but they must have the deck milled down to reduce the combustion chamber to a 305 size.
The vortec 305 heads end in 059.
look for the #062 heads they are ground with the standard 3 angle instead of the single angle the 906 heads have better flow on the 062
Craig mac, 062 and 906 heads are 350 vortec heads. The 059 were vortec 305 heads like he was asking about. 059 heads had a smaller combustion chamber (like 58 or 59cc IIRC).
So who makes the Aftermarket Vortec heads? Who sells the best deal?
Do you have a video comparing the aluminum LT1 head to the Vortec head ?
Great videos! Can you drill/adapt the vortec heads to bolt on an old style intake manifold? I have an 82 corvette with the crossfire. My plan was to get the renegade intake and a nice set of heads. Possibly port out the throttle bodies also. Or do you think a performance style aluminum head would just be more cost effective?
Yea go with aftermarket aluminum heads
Thanks for the advice! 👍
And would i need to tune the computer with all the upgrades i add to the engine?
M D most definitely!
Can you suggest a cam for a truck I use for plowing that I don't have to have the valve bosses cut? I have the heads bolted down and don't want to take them apart to send them to the machine shop. I'm using a 750 vac. secondary carb. It will be a flat tappet setup too.
Call jegs and tell them what you have and what you want, the tech guys know there stuff
OK Thank You!!!
I have a `91 Silverado....tbi swirl port heads...NO BALLS at all....can you do a video on swapping out the garbage and adding the vortec goodness...I saw the Engine masters episode too..will use aftermarket heads..lit the fire in me for the swap. thx..keep up the vids!!! My engine was a rebuilt 350 5 years ago.
It's actually pretty easy you do the same thing all you need is an intake edelbrock makes one that takes your throttle body instead of a carb other than that it's all about the same as the video you will need to have it tuned if you go with a bigger cam but any dyno tune shop can do it pretty easily
I'd like to know if u sell vortec marine heads?
Steven Zdziebkowski I have a source that sells stock replacement Vortec heads they will work on a marine engine the heads were not much different it is the short block that was quite different they are $ 700 a set finding good factory castings is nearly impossible to find
what about 454 vortec heads
I'm considering getting Vortec heads for an old 305 of mine from 1992, I had read that the intake manifold bolt pattern and angles are different and thus require a dedicated Vortec fuel induction system. Could I slap a '91-'92 era TPI intake manifold on the Vortec heads and it work just fine, since in '87 they already switched the bolt pattern/angles on their stock intake manifolds and heads? I'm trying to build for lower end torque from this 305 as well, so whatever aftermarket or stock multi port fuel injection system worked best for a 305 throughout the power curve to 5000 RPM would be great info too, I'm afraid I might be searching in vain. Thanks in advance.
A factory TPI manifold and Vortec heads have different bolt patterns, the Vortecs use 4 vertical bolts rather than 6 angled bolts like gen 1 small block heads. That being said I believe there are aftermarket TPI base manifolds designed for Vortec heads. Also, always remember that a Vortec head has a different port than a gen 1 sbc head, it's taller and more narrow. The factory TPI intake wouldn't be a perfect match anyway. Sorry bud!
Yep, I did some few bit of research, the term Vortec came out around '86, but true Vortec didn't come out until '96. There's some differences in Vortec blocks as well, but it's negligible. Scoggin Dickey is making a factory style stock Vortec TPI intake manifold, and pretty much any company that makes aftermarket intakes also make Vortec style, the Scoggin Dickey model is going to be the one that requires the least amount of modifications and tuning to get right. The real question is what are the differences between 520 and 059 factory cast 305 Vortec heads, I've seen valve sizes vary between 1.84" and 1.94", and runner lengths going all over the place on forums.
I could be wrong, but I've heard the Vortec 305's used a TBI style, "swirl port" head. I'm not familiar with them, vintage iron would be the guy to ask, hopefully he weighs in here...
The 059's I've heard have swirl port, while the 520's don't. I've also read on a casting number sheet for both blocks and heads that 1997 305's were the only year for 059 castings, all later Vortec 305 heads were 520s.
Sounds like you're on the right track, I have no experience with Vortec 305's so you could fool me. Hopefully you find the castings you are after, good luck!
How do the blocks compare between the the Vortec and TBI? Also are there any differences in the stroke?
Hey I like your vids, Being an OLD chevy guy I find you very informative. I am a multi ticketed mechanic and worked from light engines to truck and coach and heavy equipment. My field was to diagnose problems and just to keep the stuff running. Getting the most performance from my cars was just a hobby and in those days no internet. Now you can call male bovine poo on this " a crack in the head does not automatically mean junk".Cummins denied warranty on cracks from valve seat insert to the injector unless there was either compression leakage or coolant leakage. Another example, Pontiac Quad4 engines white froth around the dip stick, heads would get pulled and cracks from valve seat to spark plug hole were found. Head is condemned, they all craced there and NO coolant leak. What engineer decided to put the crankcase vent on the dip stick tube DUH. Then unscrupulous mechanics would capitalize on mechanically challenged customers with unneeded repairs. Anyways a monkeys but doesn't have a crack does it work any better?

A marine Comp Cam also installed. BUT I would like to use the stock 2 piece intake and throttle body because of simplicity. I would also have to have the ECU's remapped. AM I LOOKINH AT THIS ALL WRONG?
i am getting back into the engine building business. your info has been great . whats valve diameter on these? and are they comparable to the old turbo heads street wise? or can they be modified to do so?
they are 1.940/1.500
The Vortecs LT1 port eclipses the old turbo casting even if the turbo is ported, the vortec is tough to beat below 0.470 lift
What brand are the aftermarket heads if you don't mind my asking ? Maybe a part number.

Thanks Dan.
engine quest
I was looking to do a budget build for my 79 K10 pickup. It's got the original (as far as I know) 350 in it. My machine shop has a pretty reasonable package on a rebuild of that core. But I was wondering about going to a hydraulic roller engine. I had thought about doing the L31 but there are no provisions for a mechanical fuel pump in there and I don't really want to go electric due to simplicity reasons. I was wanting to know what your thoughts were on a hydraulic roller block that will use old style or Vortec style heads and have provisions for a mechanical fuel pump. Maybe a TBI block with Vortec heads? I've seen some sources claim those blocks supported mechanical fuel pumps. I know the ZZ4 crate block would work out nicely but It's more money than I want to spend for what this build is intended for.I don't mind paying the money for the aftermarket vortec style heads. Just wonderinf if the juice is worth the squeeze or I should just go with the OE style flat tappat setup.
just loose the fear of electric fuel pumps and go full roller vortec,more power,better mileage,proven combination
What is the part number for these aftermarket vortec heads?
8675309
I promise to stop bothering you after this one ...I have a set of 062 Vortec heads going on a stock 1982 Chevy 350 engine... you said get a set of OEM Head Bolts...are they Stock Head Bolts for the 1982 Chevy engine or for the 1998 062 Chevy Vortec Heads (if there is a difference) and what Head Gasket would you suggest...it's all mainly stock except the Vortec heads. I have already ordered the MS 98000 T Intake manifold Gasket you suggested for Vortec Heads ! Thanks again...You Rock Brother !
If I enlarge the intake and exhaust ports to fit the gaskets or will that hurt the flow characteristics
it's called match porting do it only on the intake ports
You have options to port deoending on what intake you are using, you can use the felpro 2205 or 2206, or the felpro raised runner gaskets. You will have to port to the gasket you are using. After you port match the opening, you are still limited to the smallest part of the runner. But you will flow better by port matching vs. not.
hey myvintageiron,
Have you ever used ProComp heads on a SBC build? I know they are China heads and the assembled ones are put together with junk parts, but i think that if I were to buy them bare, then rebuild them with all new everything they would be ok for around 525 horse. What do you think?
+XplicitVoltz Yes Pro comp heads are decant good choice for low budget build they are better than stock
