Cylinder Head Flow ????? I have a couple question about cylinder head flow numbers. I am seeing heads flowing in the 300cfm range and I was wandering if anyone has flowed those heads with the manifold and throttle body on it. This is how my cam grinder wants the flow figures. I have done this on a couple carbed engines and we have seen the manifold and carb cut the flow as much as 20%. So does anyone have those numbers? I would like to put a 6.0L into my 71 Nova and I think this is going to be the best choice.

However, since every head is impacted the same, the flow numbers in the chart are still a good indicator of the flow characteristics of each head...
