Well, look what we have here!

There is WAY more to making power than flow.

Agreed

My W-5's went 355. If I had another pair to start from scratch I could add another 20 to that on a 2.08 valve.

Your the only guy I have ever heard that has had a W5 go that high. And your claiming another 20 cfm with a move from 2.02 to a 2.08?
Yea, Ooooo K then!

That head at 315 won't make as much power as a W-2 at 280.

I’ll await your dyno results.

I do realize there is more to a head than flow numbers.
