Comp Cams has a new Ultra Pro Magnum Series chrome moly steel rocker that uses a 1/2"-20 stud, for the big block and small block Chevy. It is the result of some serious efforts by Tim Cole and myself since the roller rocker rule was announced. The new rocker accepts an ARP Pro Series rocker stud that is 1/2"-20 on top as opposed to 7/16"-20, made exclusively for Comp Cams by ARP. The rockers are rebuildable, and the body is guaranteed for life against breakage.
