If you want ultra power and high revs then get the 4V heads with small chambers. The 4v heads have HUGE runners, but not all have high compression combustion chambers(quench chamber). I dont think that the 4V's would be very streetable because the runners are larger than AFR 205's I believe. The 2V heads have a smaller more streetable combustion chamber.
SmockDoiley said:Trust, you do not want to use the 4V's for your small 302 because they would be reserved for 351 strokers like 392's and 408's. The 2V's are better for you and still flow great like an AFR 185, and they have bigger valves than AFR's. Also, do not use the cleveland bottom end because they are grenades with piss pour oiling. That was the catch with those things, great power and ungodly flowing heads with crazy rpms but a bottom end that couldnt handle it.
