Product Overview
Proper rocker geometry helps transfer camshaft lift to the valves. When changing rocker arms, stud size, pushrod length and spring clearance must be checked so the geometry stays within safe limits.
Confirm stud diameter, rocker mounting type and cylinder-head compatibility. The stated ratio does not make the kit a universal fit for every modified big-block head.
