SS roller rockers EQ heads

Kind words @JDMopar thank you. The Chevy pedestal mount rockers do work on a magnum with a conversion stud. I believe ARP makes it. I have never done it but lots of people have. That would give the OP the choice of whatever rocker he could dream up as I’m sure there are hundreds of different rockers for small block Chevy stud mounts.

This used to be the easy button, but crane is no longer in business, although there are other ways to get there.
