COMP Cams shaft-mount rocker set for Chevrolet Small Block with RHS heads uses 2024 aluminum rockers and an 8620 hardened steel shaft to add mounting rigidity and valve-train stability. With a 1.6/1.5 ratio, the shaft system improves cam-to-valve power transfer more efficiently than stud-mounted rockers, helping free up horsepower and resist deflection under race conditions.
