Heads
What would be the best heads to use on a 350 with Speed Pro (h617cp) dome pistons? I already have the block and pistons and everything. I know if i use heads with around 64cc chamber the compression would be to high. The engine is going to be in my daily driver. Also, what cam would be best?

But yeah, your main issue right now it seems like, is your Combustion chamber size. Someone else can chime in and give you a more accurate number, but I think you can use a 78cc and get a decent compression. I see on here alot, that the guys running an Holley Stealth Ram intake use AFR 190 heads, so I'm assuming that's a nice combo. Be a little more specific as to what you are looking for in terms of price, mileage, performance, etc to get a narrower answer.

76cc chambers will bring you to about 10:1. That leaves either smogger crap castings or aftermarket.
IMO domes are a bad choice for street cars.
