The best thing you can do is not listen to anyone here. Me included. When you are ready to do it call Brian at IMM or Brett Miller. Those 2 will steer you in the right direction. Also, go on YouTube and watch Eric Weingartner. He is a Chevy guy but his knowledge applies to every head. I can tell you this though. CFM does not equate to horsepower. Its a good indicator but its only 20% of the info. Chamber design is huge and if you look at all that's out there from the Chinese heads or edelbrocks you find the chamber is a disaster. This hurts power big time. Just another piece of the puzzle. You will not find a cheap head that flows 350 cfm. You will need a W variety head with expensive parts to go with.

Right he should get with a reputable builder because its not just head flow. If he has a short block already built he will need to get a head with compatible chamber CC, get the builder to recommend cam and valve springs, and match up the rest of the combo like intake header tube size etc etc ect.

When I built my small block stroker I had Brian at IMM tell me what would work what wouldn't and got advice on the overall combo not "what heads should I use". Its not just the heads, one should not be looking at one component, you need a match set of components so that it all works together and teaming up with a reputable expert would be able to guide you there taking your budget and goals any existing parts you want to reuse ect ect ect into consideration.
