Speedmaster head hypothetical
I'm working on a couple of heads/ports starting with bare Speedmaster heads. Pictured are the specs on two different flow bench runs. If these heads are used on a 408 for street or street/strip, which would you choose? In my mind the answer is clear, but I know some of you racers and dyno guys have experienced a lesser flowing head making more power. Is there any way that head A outperforms head B, and why? No other changes between motor pulls, just changing the heads. I know, I know - timing might need to change, cam might need to change, carb might need re-jetting. Let's keep this simple. Given the information here, is it reasonable to say that head B is better, or is there just not enough information?
