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


Interesting comment. The Indy heads are pretty much aluminum W2 heads.
Would rather run them any day of the week than W2’s. Depending on which flavor, they have a good bit more potential than W2’s as well.
And, aluminum you can fix.
