I use 1.6 PRW stainless rockers on my RHS heads, as recommended by Brian at IMM when he built the heads for me. They've worked great for almost 10 years - no problem. The rocker sweep is dead center and very thin. Cam is a HFT .561" lift with the 1.6's.
Another option is to use the rockers you have any call up b3 (
