Cometic Oldsmobile Gen-2 Rocket V8 .045in MLS Cylinder Head Gasket - 4.200in Bore

When you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, a reliable head gasket is crucial for sealing combustion chambers and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, offering a robust sealing solution for a wide range of vehicles including Buick, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 80s.

Cometic constructs this gasket using multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material designed to perform in harsh sealing environments. This construction means the gasket requires no additional sealants, making installation more straightforward. The center shim layer can be varied to achieve different thicknesses, and this particular gasket has a compressed operating thickness of 0.045 inches with a 4.200-inch bore, designed to match your engine's specifications.
