Re: 077 aluminum heads
Flow benches give you a lot of good info, but they are not the end all be all.. To Marv's point there is good info to be had with them, but flow numbers do nothing if there is a huge valve with bad valve angles and hogged out ports compared to a head that has a little less flow numbers yet smaller port/valves to keep velocity up. Reversion can be the enemy at low RPM. Add to that, the cam profile needs to be matched to the heads, intake and exhaust.
With out comparing the full setup it's a crap shoot.
