The COMP Cams timing cover gasket for the 217 Chevrolet GEN VI Big Block reduces timing cover flex that can cause erratic ignition timing and lets the camshaft be replaced without disturbing the oil pan seal. It offers simple endplay adjustment via a dial-indicator access hole, an integrated timing pointer for easier ignition checks, and compatibility with all water pumps and most gear drives.
