Man !!! .. my old 627 lift roller cam 340 /W2 head 12.5 to 1 compression I shifted at 7,200 ran 10.70s... now I am only shifting at 6,000 / 6500 leaving at 2,000 .. I guess I should mention that my car is slowed down via throttle stop to run 11.50s at 114 with 1.49-1.51 60 ft... I really like the W2 heads I wish I had them on my 408 instead of the Indy 360-1s
