Steve I would love to try a set of my w9s on your car what's your valve free drop and chamber volume ?

Are your heads rolled?

About what is your port opening hight and width?

What valve size intake and exhaust seat angle?

What length valves?

Stem size of valves?

What bore size are you at?

What rpm do you launch and shift at?

Cam may need changed but I would love to see straight up swap my heads vs your heads.
