Stainless, Bushed PRW Rocker Arms

bushed rockers require a banana groove on shaft, also oiling holes have to be angled down at 15 deg like factory shows, also, hyd cam with 1 turn preload is too much, best to run zero preload, i was informed by rocker outfit, roller rockers were not meant to be used on hyd cams, use on solid lifter cams, valve lash lets the roller rotate and not wear out, hyd lets it rock back and forth, in same spot causes wear pattern. just food for thought.
