Cometic Oldsmobile Gen-2 Rocket V8 .036in MLS Cylinder Head Gasket - 4.270in Bore

When you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, getting the cylinder head gasket seated correctly is crucial for sealing combustion and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these powerful V8 engines, offering a reliable seal that won't break down under pressure. It's designed for a 4.270-inch bore and has a compressed thickness of .036 inches, making it a precise fit for many applications.

Cometic constructs these MLS gaskets with multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction not only provides excellent sealing but also offers increased strength and resistance to corrosion, which is important when mating aluminum heads to cast iron blocks. Because they're designed for high-output engines, these gaskets don't require any additional sealants, simplifying the installation process.

This gasket fits a wide range of vehicles, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 1980s. It's a well-built component that helps ensure your engine rebuild is sealed up tight and ready for the road.
