Nice.
Edit. 300 CFM on a 2.02 valve tells me several things.
1). The valve job has to be pretty damn good.
2). Whatever port work was done was done correctly.
3). The package is very efficient.
4). HP/CFM should be very, very good.
I hope the intake manifold has been worked over to compliment the heads. I could see an easy 650 HP out of those heads IF the combo is on the money. That's killer for a 2.02 valve.
