Gasket Matching Tools, Tips, and Tricks
HTML-код
- Опубликовано: 29 июн 2024
- Is gasket matching, or port matching worth it? Personally, I think so. I recently gasket matched the intake, cylinder heads, and exhaust headers on a 383 stroker and I have to say, I’m very happy with the result. The engine seems to run smoother throughout the RPM range. It also seems to pull a bit harder. I can’t say exactly how much power it was worth, but it did feel like an improvement over just bolting those parts together. I plan to do this to every engine I build going forward.
In this video I cover the tools and processes needed to perform a gasket match, or port match on your engine. This information will apply to any gasket matching situation no matter what the engine displacement or design. I hope you find the info helpful.

Completely right Eric: the key phrase here is "aim for smooth transitions". For daily drivers there is no need to change the passage shape too much, just remove any casting imperfections and as you said, sand and polish the exhaust so gunk has a harder chance to stick into.
PS: for cleanup phase if you don't have a pressure washer, you can go with compressed air, mineral spirits and lots of coffee filters as they don't leave any lint. Patented tip from our friend Jafro hahaha
This grows to a habit very easily. After a few heads all the little casting defects will hurt your eyes, every small ridge feels like the sharpest knife to your fingertips. You will feel deep inside that something must be done about them.
Today I worked on my motorbike's intake ports.
Try a flame tip burr Eric!
reminds me of my buddy Jim Bell back in the 60's and early 70's,, he was a engine freak as well as myself, except he went into as a living. went to work for Houston Balancing and engine service, and branched off into nothing but heads.
I'd go to his house and he'd made a trip to the junk yard and picked up a pile of small block chevy heads and drag em home and start porting and polishing. He had a pile of heads he'd killed by breaking through the wall of the ports. You could get these heads cheap back then, sometimes the junkyard would give em to you.
He went on to his own business later on in nothing but heads, I think he called it Bell's porting and polishing or something like that. Sadly he died a few years back, and I really miss him, we'd lost touch as we aged and when I went to look him up come find out he'd just died the month before...
Rest in peace Jimbo...
Sorry to hear about your friend. He sounded like a really cool guy.
I love that Bill Burr mentions you on podcasts, you have saved me thousands on my sons 99 Acura. Thanks dude!
Welcome back Eric. I hope you enjoyed your break. So happy to have your uploads to help us Stay Dirty.
Thank you! It's good to be back.
The non-ferrous ones will take a more aggressive cut. You'll get done faster, but you may like staying with the ones you have since you want to creep up on your lines gently.
You said it. I was going to make the same comment. I have various non-ferrous cutters and these hog stuff out right now
I'll probably never be able to do this, but I'm still giving this video a like
you can definitely do this yourself! Prussian Blue layout fluid/dikum carbide cutters and a bunch of cartridge sanding rolls takes a lot of time but definitely worth it! anybody can do it just take your time!
If you got heads off start with oil return galleries espcially on cast iron blocks. Plenty of work to be done at least to steady the hand and get use to the tool
I just did a port match on my engine. It did make a bit more power. Great video!! Keep em coming!
I sure like the way you've organized your peg board. Cool to see socket sets hanging vertically.
I don't love putting them there though. I think the space could be better utilized. There are actually some more tools on the way for this 'work station'. After they show up, I plan do redo it. Happy New Year.
Thanks Eric. This information is extremely helpful that I’m at the prep stage and still learning everything I can about porting and polishing.
I’ve not done this for years and seeing it done again is giving me the itch to do it again
My lower intake manifold is ported, polished, and gasket matched👍you guys making power this is something u definitely wanna do😉
One of the best tools in the hotrodding tool belt! Be well Eric. Happy new year! Great vid as always.
I enjoy doing this kind of work. Its meticulous, time consuming, and peaceful. Good way to lose yourself for awhile.
Also, super pumped when I saw a new ETCG vid. Hope dads trucks is running great
I really got into this for the very reasons you mentioned. Mondays ETCG1 will have the latest update on the truck. It's running amazing BTW. In fact, I'm taking it out for an aimless drive today just so that I can enjoy it. Thanks for the comment.
I had planned on doing gasket matching on my old ford truck intake/exhaust in a few months. Thanks for the info.
Don`t rush, things can go sideways quick. I have a buddy that can confirm this, he went balls to the wall with a grinder and hit a water jacket...no bueno, had to replace that head and start all over. Great tip on the regulator and different bits Eric. Thanks for sharing. Stay Dirty.
Thanks Eric for the info. I've been watching your videos around the time you started and I have learned alot from your instructions. One of my favorite videos is the 5 series on the Chevy SUV 5.3L engine swap back in 2011. I guess cause thats the same engine I had for a long time and I'm currently rebuilding a 5.3L in my 05 Silverado. Keep up the good work and thanks again!
Happy New Year!
Good to see your back!
Happy New Year!
Love the great work. Kind of having a though time on what to do with my reliable pos when I replace it in a couple of months
Actually been wanting to try this with a salvage yard head. Every engine here on out makes me really want to do it!
Very informative! A few weeks ago I practiced on a cheap, temporary exhaust manifold I had to install on my car until I buy headers. The part about practice on something that’s not critical is key to this! I now have an oil pump that the manufacturer suggests port matching the oil pan holes to the gasket to maximize scavenging, so that practice on my exhaust manifold was beneficial for this oil pump job.
Love this content. Thank you Eric!!!
i just love listening to this guy
Great video! Little thing I picked up along the years, if your bit becomes clogged, you can use an old block of wood to clear the flutes. Reverse works best but even in forward does the job. Just get the bit spinning and touch the wood. 👍
Amazing the difference this can make. I gasket & port matched the throttle body to intake to head on my Honda Del-sol. Wow what a power increase & it didn't hurt the mpg at all.
About to do this on my 96 accord
That was inspirational. Thank you for posting this vixeo.
Those are the best horsepower gains. Ones that cost no money, but just take a little bit of elbow grease. 😎
Since I’ve replaced half the driveline on my Silverado over the past 104 thousand miles, my next project is going to be a supercharger, once the engine is bulletproofed. Only stock parts of the driveline are the engine and transfer case so far. Once my lifters fail, I’ll get started on the engine. Should be soon, LOL.
The new transmission is sweeeeeeeeeet! I never realized how bad the stock one was, even from day one. I hauled my first vehicle with it last week - a ‘77 Bronco. Never knew a transmission could work so good! Very happy with that purchase at least. 👍😎
Glad to hear you have the transmission sorted. Yea, everything working together makes a big difference. Good luck with the engine build.
@@ericthecarguy - Thanks, Eric. It’s going to be a while. Have to let the funds recover from that transmission. It’s got the best of everything inside, including five pinion planets. It was a little spendy.🤑 😁
Happy New Year, Eric! Great to see you back. Looking forward to what's to come from ETCG in 2021.
Happy New Year! I've got a lot of cool stuff liked up. Should be a fun year. Take care my friend.
@@ericthecarguy Great news! I can't wait.
Great Video!! I'm grateful that I found it! Thanks!!
Thank you Eric I always enjoy watching your videos I am from South Africa
Excellent video!
i am about to port match my aluminum head soon so this is good info friend ... peace n love broski stay safe keep it rad and build on 💪
I am new to the car world. Been doing weekend warrior stuff for a little over a year now. I'll wait to try this for a couple years.... Ha ha
Weekend warrior sounds better than what I do.
I diagnose some stuff, replace fluids, and some parts for 20 bucks a pop. Ha
One key here that I didn’t hear you mention is that matching the head side of the intake is most important. You don’t want to run into a “wall” or lip. If the intake manifold runner opening is already smaller than the intake runner port on the head, and you don’t plan on hogging the entire runner of the intake manifold out, you don’t “have” to work on the intake manifold. Sounds odd but if you create a double bell or bulge where the intake and head meet you could actually be slowing air down instead of speeding it up. Guys with dual plane intake manifolds will want to pay special attention to this. Another note, if my comments apply to you and you want all our horsepower, it may be time for a new intake manifold. Thanks for sharing Eric!
Well said, looks like this particular "gasket matching session" only succeeded in creating a large area at the gasket face and could be (probably is) killing velocity through the port. The goal is to port match, not hog out to a gasket, gaskets are inconsistent in their sizing, even the more expensive quality gaskets. Especially when afr says in bold text in the literature that comes with their heads "DO NOT GASKET MATCH THESE HEADS"
@@b.c4066 . Right. I like this guy and he knows his automotive stuff. But leave the head porting to someone more knowledgeable on the subject unless you want to mess around with some 882s. Those port entries are huge! Matching all the way to the gasket is not only overrated, it's hard to get the head, gasket and intake dead nuts on assembly. I was where he is a few years ago. But otherwise he is a very knowledgeable mechanic.
Nice informative video Eric On Gasket Matching @EricTheCarGuy
First time I did this I was really surprised at the power gain.
Well worth it.
Nicely done 👍
Can be good to mention that one should not enlarge the exhaust port other than in the roof och the port.
Thanks for the video 👍
Great video 👍🏻
Dammmmmn Eric that money shot on the valve ports!!! Looks legit
I've done this sitting on a stool with the cast iron heads on the top of a 13 gallon bucket. I think I used all abrasives which is doable on cast iron.
my 1964 Buick 310 V8 wildcat came from factory port matched, heads and intake! which is why I beat every stock gt mustang up to 2001!
If I could add one thing, it would be to put masking tape in or over the tapped bolt holes to keep tiny bits out of the threads. Form it into little ear plug looking pieces and put in the threaded holes. Do the same for the water passages.
Pressure washing and compressed air after you work pretty much takes care of that. At least that's the point of cleaning after you're done. Thanks for the suggestion.
yey Eric is back :D
nice video!
Blueprinting may give You (a little) more power :)
Your work seems much like what I've done to my setups
Thnx
Nice job
What incredible advise Eric, thank you. Especially the practise method to familiarise yourself with the tool, that's just golden! Could I use a Dremel Tool for this?
Sounds nice at end of vid specially when it catches second
Did lots of work measuring with a Superflow Bench. Used to measure everything. Even ported a carburetor (not worth it). With an aggressive 427 with set of 1.88/2.19s 049s I finally watched it become a self destructive little animal on a dyno with a solid cam along time ago there was nothing to stop it from either floating out or losing airflow. (newbie on the Dyno just let it rip till it went kaboom) It pushed its power band so high up the it murdered the low end torque. (and eventually the entire top end) Under the curve is more important than max airflow IMHO. With a long stroke engine like a 383 the runner size is more important then max flow as it doesn't need as much airflow as a 3 inch stroke mouse engine to make power at a given RPM. I haven't ever ported mouse heads because I was always too busy with the porcupine heads on rats which in all honesty needed less work than mouse heads by their very design differences. Our air here is so thin here at 6000ft, velocity is more an issue than sea level where the air density is immensly better. The very most important tool when porting is Safety glasses.
awesome video eric ! I have 2 spare b18 heads laying around for my Acura integra.. I want to gasket match them and maybe port and polish but I've been scared too because ive never done it.. I called 3 machine shops where I live in Mississippi and no machine shops will port and polish for me.. they say "it's too time consuming" and brush me off.. I've watched your video and I think I'm gonna give it a try ! thanks man ! stay dirty !
Just gasket match, I would avoid 'porting and polishing' as you could damage the head in the process. Also, Honda heads flow pretty good right from the factory. Good luck.
Bill Burr gave you a compliment on this week's Hot Boxin'
You really made us wait for this one.
I am entitled to some time off for the holidays don't you think?
@@ericthecarguy Definitely. Maybe this year onward you should record some videos in advance and tell RUclips to make them available during the holidays. LOL.
Bill blur sent me here....
Fascinating stuff
labour intensive for sure ...... but every little bit helps! cheers.
Hey Eric, Bill Burr just mentioned you on Mike Tyson's podcast. About an hour in. It was pretty funny
59:20, I was curious and determined to find the timestamp lol
Erick the goat guy Meet Eric the car guy I think I work on cars more Did these days
I'm constantly amazed that modern manufacturing the way it is these days (i.e. computer designed to within thous') that this kind of 'rough' matching still exists...
You and me both.
Those afr heads are normally "as cast" heads. After the cast the head. They just do a quick clean up on them to make them work good enough. The real money is in CNC machined heads that are put on a machine that makes the ports perfect but they are hella expensive.
I know this is an older comment, but for those like me that just found it, I'll reply. I think the close tolerance machine would be time consuming and expensive for the manufacturer. They want to quickly and inexpensively mass produce everything. They are in it for profit. Besides, if everything came perfectly done, we'd lose our hobby and love of making things work better. Hot rodding would die off and we would probably all just become "parts changers".
Artist style!
Thank you 🙏🏻
I did the same thing with my headers and currently doing all this and expecting big returns. Good video but what grit sand roll did you use?
😎 thank you. 👍👍
All the years I have worked on vehicles close to 40 I have always sent my heads to a professional machine shop. Even the current mechanic iam working with sends them out.
Nice car!
It’s a bit like dentistry WD 40 sounds good to use , I guess there’s some chemicals not to use on aluminium . Thanks Eric always learning .
Minor (pointless) nitpick, it's probably best to say it as ' the processes are the same, it's just that the goals are different'. Porting (that's how i heard it) after all came from gasket matching back in the day.
Eric, thanks for another great video and showing off some tools I haven't seen. Those stands to hold the heads are cool. Anyway, I assume another video is coming, but I don't want to wait, so I have to ask, did the rebuild work? Have you solved your blow-by problem? I look forward to the video. Stay dirty. -Alex
All of your questions will be answered in Mondays ETCG1 video. Let's just say I'm very happy. Thanks for the comment.
Learn something new every view.
Hey Eric, while were on gasket matching the heads for some performance gains, what about Indexing your spark plugs + Side gapping your spark plugs? That's another modification i made to my spark plugs and had a noticeable idle quality/acceleration/Potentially better MPG'S!
When will you begin the foxbody, since you got it as a donor car I’ve been waiting... had my 79 for 9 years now... saw your fairmont build along the way.. but I went LS.. how is the fairmont????
lmao the narrow lettering. I thought it said "Hatching" hahaha
doing this is so satisfying, let it take a week lmao. gunna ask my buddies to let me practice😂😂
Hey Eric how come you can't just trim the gasket to fit the holes flush?
You guys that are not going to pin / align the intake to heads....Eric did not say to leave the intake manifold ports a bit smaller than the head ports. The little step will not hurt flow. < because of flow direction.. and will be way better than the other way around.
Do you port match the coolant passage also? I have a #906 Vortec head and there is ALOT of material within my blued scribe mark. Intake gasket is out of a kit. "Problem solver gasket" i was told. Plain metal core with black rubberized molded gasket around port.
Probably a dumb question but is a tune necessary after gasket matching or is it just flow
What gasket do i use for my edelbrock performer on iron eagle heads? there is a gap at the runners. Seems heads were milled before i got them.1970 350cu
Eric, Have a 03 Regal GS w/sunroof that opens but will not close. I'm looking for a wiring diagram to trouble shoot problem. Any suggestions U may have would really help, thank U in advance.
What about newer engines that use o-rings?
I think you will gain north of 25hp... Also it will climb thru rpms easier and more efficiently which if you're trying to go fast is important. Good job
I am currently doing a full rebuild on a cylinder head. Do you have any tutorials on replacing valve guides? Those brass ones
Not at this time. An air hammer with the correct attachment is your friend. You'll likely also need to ream it to the correct size so you would need those tools as well.
@@ericthecarguy Thank you! I was afraid I would need a reamer to do a proper job. Thanks
The “Incredibles” 😜
Port matching would be the appropriate term.
Great video, can today’s plastic intake manifolds be matched? 👍😁
I would not recommend doing this with a plastic manifold.
@@ericthecarguy I kind of thought the same thing, thanks for the reply
Yes you can. Plenty of people and companies do it successfully.
Pls do another civic video
I love you bearded magic metal man
Could one use a Dremel rotary tool in lieu of a die grinder? I know there are obvious differences like size and power, but I have no type of air system setup at home but do have a Dremel.
I did this years ago with a drill & stone bits. It did take a l o n g time and was really dirty. I was planning on doing this with a dremel too at the end of the larger removal steps. Good luck!
Thanks, this is a project vehicle I'm doing this too, so time is something I have plenty of. I'm thinking the time spent is going to be the biggest difference between the 2.
You might get away with a Dremel, but a die grinder would be much more efficient if you can swing it.
Maybe it'd be worth it to put off the project for a few months and save up for a small air system then.
I'm in no rush on the project, winters up here in Northern Ohio are a bear in unheated garages
Are you gonna dyno to see how much hp you got. I wanna do a dimple port job on my intake side of the head because I know it'll add power for sure
At some point yes. Sadly I didn't do it before doing this work to see what the difference is. Dyno people are hard to get with as they are always busy it seems.
who all remembers when Eric got the car lift?
Eric I watch all your videos bro. Do you think you could help me out please?
I have a 2001 V6 Honda accord four-door. When I start the car and it’s cold especially when it’s cold it won’t come out of first gear until it’s warmed up for about 15 minutes. In the winter time it gets much worse. After about 15 minutes warming up the car drives fine.
Shift solenoid? Bad ground?
Could also be fluid related. My car literally grinds gears unless you warm it up first.
But you also kind of have a bad year, try carcomplaints.com if Eric doesn't know the exact issue immediately.
www.ericthecarguy.com/solving-transmission-problems/
@@felixgato4392 I will look into that.
Whatever my problem is it’s got to be something simple it’s been going on for over two years now and it’s just getting worse at first I thought maybe it was a shift solenoid I’m not so sure someone’s that may be a vacuum line??? But I’m not sure if that applies to this year car. I started working on cars about five years ago by using RUclips so obviously I don’t know to much.
I was hoping Eric would be like replace this and I could go buy it and replace it LOL I know it’s not that easy all the time.
Like I said it’s been going on 2 1/2 years and every year it gets worse now it requires time in the summer to even warm up. Before I didn’t have to warm it up in the summertime.
@@Oblithian Eric the car guy responded with has transmission troubleshooting guide. I was really hoping he would be like “ oh yes that’s a common problem with a simple fix.
But no luck 😔
Couldn't you use an old gasket/sacrificial gasket and paint the gasket with the blue dye?
You're machining the metal, not the gasket. I might be confused about what you're asking.
I'm curious as to what you'll understand with this question........What makes the Gasket the Boss? Should we trust the Gasket maker, or the Engine Manufacture?
As someone who’s unfamiliar to this, I’m now wondering why are gaskets made bigger than the holes and not matched perfectly?
I am fairly certain it is tolerances. The head are cast so it is hard to make ever cast the same. If the intake runner is a little bigger the gasket isn't covering the runner. Also, with small block Chevy engines, there are probably hundred of different head designs but many of them use the same gasket so the gasket manufactures make the gasket for the big hole.
It's rare that parts match up perfectly in my experience. Especially with mismatched aftermarket parts like I was working with here. Edelbrock intake with AFR cylinder heads.
Im starting to think we will never see the unreleased fairmont videos.
I have tried and failed several times over the past 3 years to find an editor to help with those. Sad truth is, I simply don't have the time to produce the weekly videos that I do and also edit that footage. I hope that changes someday.
As the old saying goes; the devil is in the details. Eeking out that last little bit Of what is possible. Makes me think a lot about the difference between Street and racing. Between assembly line and extremely limited numbers.
Back in the early 70s I made my gas gets out of Cheerios boxes 😃

" Rome wasn't built in a day "
Nope, it took a couple of weeks at least. 😉
@@ericthecarguy Oh yes, the stone masons were out on strike because the sponge on a stick in the defication area was not up to roman bum wiping standards.
Picky buggers :-D
🤣
Couldn't there be a different gasket match depending on the brand of gasket ?
Yes. Most people will refer to the gasket part number as the size they match it to. I.e. "i matched my sbc heads to a 1206." Referencing a 1206 fel pro intake gasket.
A fan of gasket match porting...
Not a fan of porting and polishing unless a flow bench is available....
