All Pro head, BIG #'s

Was at a local guys shop picking up some work and saw an all pro head on the flow bench. NOT ported by the guy flowing it. 370 cfm at .700 through a 2.12 valve on a 4.125 bore. I am going back tomorrow and will get the entire flow data, I was in a rush today. No bullshit, and not trying to promote anyone, just passing on info.

Bob Williams said he made some changes to the head casting but, daaum!! Demz good numbers! The AllPro heads we prepped a while ago flowed 332cfm peak @ .650" lift and the runner ended up at 248cc. They start out big and end up really big. the valve size was 2.08"/1.60". Keep us posted.

Intake Exhaust
.200 140 .200 100
.300 211 .300 151

.500 313 .500 226
.600 344 .600 240
.700 375 .700 246

Big solid roller setup, very aggressive valve job, deisgned to flow to the .700 mark and go sour. ~255cc intake runner, dont know exhaust.
