The COMP Cams hardened, black-oxide coated guide plate is a flat, one-piece design for Pontiac 350–455 engines using 7/16" studs and 3/8" pushrods. It provides a durable locator surface suited to high lift and heavy spring-pressure valvetrain setups and is produced to maintain accurate stud placement and reliable contact points without adjustability.
