This full set of eight COMP Cams guide plates fits GM LS cathedral-port engines (examples: LS1, LS6) with 8mm rocker studs and 5/16" pushrods. Hardened and black-oxide finished, the plates are designed via stereo lithography for accurate stud placement and rounded contact points, providing stable pushrod guidance in high-lift, heavy-spring valvetrain environments and replacing components for select Ultra Pro Magnum kits.
