Default 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.
