COMP Cams shaft-mount rocker shafts for Pontiac V8 with P8 heads use 2024 aluminum rockers paired to an 8620 hardened steel shaft and a 1.5 ratio to improve valve-train stability. The shaft fulcrum increases mounting rigidity over stud-mounted options, providing a more efficient transfer of camshaft energy to the valves and helping maintain consistent valve motion under higher loads.
