This set of eight COMP Cams guide plates is hardened and black-oxide finished for GM LS cathedral-port cylinder heads and is designed for 3/8" pushrods with 8mm rocker studs. Using stereo lithography for precise stud placement and rounded contact points, the set provides consistent pushrod guidance in high-lift, heavy-spring valvetrain applications and replaces like components in Ultra Pro Magnum GM LS kits.
