Thanks Alan,
As I'm sure is for most of us, we always want to go faster !

Can't fit 7/16" pushrods in my engine... intake runners leave no room.
I have Manton .125" wall 3/8" pushrods. Lift at valve is between .500" - .510"
I have only 7/16" studs. However, I was very careful to not mill anyore from the top of the stud boss than necessary. In fact, these new rockers are very VERY close to the base.

Changing to the roller rockers is more to eleviate my intake "fatigue" problem, than anything else ( using Crane "Nitro-Carb" BBC 1.7 ratio rockers, which are somewhat tough to find now ).
