Heres an article from Mopoar muscle engine challenge they got 418 hp with these heads on a 360 , hope this helps, your right though most of the engines with these heads are strokers, on the RHS website they claim they will work on 318 on up.So i'm reading a lot of posts on stroker motors with rhs/indy heads but can't seem to find much on non stroked 360's. Just looking to see what kind of power numbers are being made.
I bet they'd really wake up a stock 318. The compression bump would make for some shockingly decent horsepower, and allow the use of better cams and good intakes.
I've been thinking about that since those heads came out...
It's crazy that no one seems to run these on plain old 360's
I have a stock bottom end 318, with the RHS heads I got from Brian at IMM. I put edelbrock performer RPM manifold and the RPM cam and lifter set in it as well, with hughes 1.5 roller rockers. I will keep you updated on how it will run once I install the engine into my car in the next coming weeks.
Can't wait to see that. I bet you feel the say way! LOL
