AFR Heads

Head porting, to me is like quantum mechanics or dark matter theory. I wouldn't even think of trying to understand it all. Maybe you're right, maybe not. But time and MPH do not lie.
I certainly have no reason to doubt the guy. Maybe he wrote the wrong numbers down?

After a full summer with those heads, I really don't care about the flow numbers. I just know they are a DRASTIC improvement over the TF's or the original hand port job. So I'm happy.........
for now.
Well c'mon and share the et and mph difference. Ya can't leave us hanging lol
