I'm not Vance - he can speak for himself. But the dudes that make higher
ratio roller rockers warn you to "adjust" your valve lash based on the
rocker-arm ratio. I think it has to do with reducing the shock on the cam
and lifter due to the larger "ramp" load - with a high-ratio rocker, the
cam is actually lifting more (or technically there is more inertial load).
Undoubtedly, someone will find error with my reply, but the Goodparts cam
sheets warn you to adjust base on which rocker setup you have. I am 100%
certain of that as I just read one on Sunday.
