I had my heads done by a friend of mine who used to work at a shop who is a sponsor here. I never got the flow numbers till now. I just thought I'd see what everyone thought since I don't know much about heads, or even act as if I do. I do know these heads picked up .4 in the 1/4 mile untuned.

These were flowed on a Superflow 600 in 28" of water.

With stock 5.7 castings 2.02 1.57 valves
