This is awesome! I read a lot of your stuff on FABO. I'm having Brian from IMM build me a set of these for my 360 with 2.055" valves and some porting. Can't wait for the results!
wow really clean engine........... few years ago I got a 360 for $25 when I open it up it to was a 60 over rebuild with extremely low miles on it. Have you had in cooling issues with the 60 over engine?
Nice work man! looking real good. Did u pull those heads apart and check them before u bolted then down? I'm just curious. I had all kinds of problems with the Edelbrock #5093 heads set. I will keep an eye out to see how those Speedmaster heads work for ya. ( hoping u post another video when you're ready) I went through 2 sets of Edelbrock heads and even then I had 3 leaky valves on the 2nd set -plus the Intake and Exhaust both need to ported out. The valve springs were to weak for my .488 lift cam. Edelbrock claims good for .600 lift. No 3 angle grind as promised - no stainless steel valves as promised. Only the exhaust valves were stainless. Edelbrock sold me lies and sub-par heads. Thinking I shoulda gone with Speedmaster to save me a lot of extra work. Good luck, I liked and subbed.
Yes, I tore them down and inspected (it's the video link at the end of this video). They checked out good, but I cannot tell what quality of springs/valves/keepers they used. Time will tell
Yes, Thank you. I saw the other video on your teardown right after I saw this one and wrote all of that stuff and asked all those questions. I feel the same way u do about motor work. At least I think were "like minded" I think that motor your working on will be a great one w/out having to rebuild the bottom end. I've done the same thing before w/the wire wheel and clean the ridges and pistons at the top of the cylinders. Never had a problem doing that. I like those headers...They look real beefy. I bet they sound great. I look forward to the restart and hear how it sounds. I wish I saw your teardown video before I bought those Edelbrock heads. They're fine no but required much work before I could run em'. Have a great day and good luck bro. Love the Duster!
Did you use the springs that came with the heads? Or did you swap them out for softer springs for your smaller cam?. I have a 480 lift cam in my 360 and was wondering with the 600 in lift max on these springs on these heads will work. Also what heads stud kit did you use? Part#
I used the springs that came with the heads. I used the speedmaster stud kit they recommend for these heads has well. I don't remember the part number.
Thanks bud this is every helpful changing head gaskets on my 360 in my 71 demon the problem I got is I got power steering and can’t clear the header over the power steering hooks up to the steering calm
A lot of that depends on which headers are used, and the way the engine sits in the car. Tolerances are 1/8 - 1/4 inch all over these cars back then. What one person battles, the next guy has no issue. Best of luck with your project!!
I spoke with Procomp about these heads and they state they oil threw the heads like factory but if you ask speedmaster they oil threw pushrods there’s no definite answer on how they oil so I’m interested to see how this turns out.
This is interesting. A mainly stock factory engine and you are 'perfing it up one part at a time and showing us the resulting difference. Cool vid! Thx.! ...PS...if its not too late, show the side by side chamber difference between the iron heads and the aluminum ones.
The heads are bolted on the car, but I do believe I showed them side by side in my "Home inspections Speedmaster heads" video. That video is at the end of this video
i'm doing a very similar build on my 318 with the speed master heads. i'm concerned about using the stock intake because it has the egr and the heads dont. money is tight and i'm wondering if it's possible to use my stock manifold
Roller rockers free up friction. Also, many try to correct poor geometry with new rockers/shims. In the case of the engine in this video, I used the factory stamped steel rockers.
1.5 is the norm for stock V8's. 318 - 360, and all big blocks too - 440, ect. Don't know about every motor but I think all V8's are the same for the most part. (the muscle car era anyway)289 - 351 Windsor - Pontiac 389 - 455 - Chevy 327 - 454 are all 1.5 standard ratio. Maybe a few exceptions here and there. But Pretty sure that's the norm.
I like the heads, that's for sure. Thanks for the detail and good pictures.
Can't wait to hear it run. Your swap will help a lot of us decide how soon we swap out our heads. LOL
Love your threads. Thank you for doing the videos too. Will be interesting to see what you pick up at the track.

Another great, informative video. Those heads are lightweight! Looking forward to the performance report.
wow really clean engine........... few years ago I got a 360 for $25 when I open it up it to was a 60 over rebuild with extremely low miles on it. Have you had in cooling issues with the 60 over engine?
no cooling issues.... not even on a hot day and no fan shroud
I did the arithmetic and with 60 thou overbore, one gets 370 CI. Nice!

@318willrun Thank you for the response. This helps me out a lot.

I turned the motor over and they oiled through the heads like the factory heads.

Nice, love it. (subscribed and kicked the bell on ya)
Great video. You sure have a clean engine bay. Look forward to your next video. Did you use the pro comps out of the box or did they need work?
Got them fully assembled on Black Friday 40% off... yes, I took them apart and inspected them (did a video on it). they were fine
I use stainless steel bolts for the exhaust manifold never had any issues
Why? Because they are super light weight and very stable being shaft mounted. Ask Dulcich. 😆
What head gasket did you use?
Fel Pro 8553
I should have finished watching before I asked!
i'm doing a very similar build on my 318 with the speed master heads. i'm concerned about using the stock intake because it has the egr and the heads dont. money is tight and i'm wondering if it's possible to use my stock manifold
I'm assuming it's a stock 4bbl cast intake?? The egr shouldn't hurt anything
Was that the original engine in the duster? Just curious thanks
Nevermind I watched the whole video
They look 👍🏼
What brand of head gaskets did you use
Fel pro
Why have roller rockers if you don't have a roller cam with roller lifters ?
Roller rockers free up friction. Also, many try to correct poor geometry with new rockers/shims. In the case of the engine in this video, I used the factory stamped steel rockers.
Any plan to get a true 1.5 rocker arm?
Probably won't upgrade rocker arms unless I upgrade the cam.
@@318willrun if you said that in the video sorry wife is sleeping next to me so the volume is off for safety.

@@guidosarducci3047 BB Chevy are 1.7 ratio IIRC.
Good Call. I didn't know that. Thanks for setting me straight.
