compression or flow?

We have a vague idea of what flow to expect from rpm's. I'd have the W2's flowed, (if you have somebody local that can do it), to find out how much better they are. 5% better, I might run the rpms. 15%better, the W2's become a no-brainer.
With your w2 intake, headers and cam, I think I would use the W2's, 100%
In MY opinion, the half point loss in a pump.gas engine is a plus.
