A fwiw, going thru my older Comp catalog at solid roller lobes looking for 262 degrees duration and 0.575" lift. Their High Energy Street roller lobe 4221 calls for 0.020" lash with a 1.5 rocker ratio.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
