Cometic Chevy Gen1 Small Block V8 .051in MLS Cylinder Head Gasket - 4.200in Bore

When you're rebuilding the top end of your Chevy Gen 1 Small Block V8, a good head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is designed to handle the demands of high-output engines, offering a robust seal without needing additional sealants. It's built to work with both aluminum and cast iron blocks, and it can handle the stresses that come from different metal combinations.

What you get here is a well-built gasket made from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and various sealing conditions. The center layer is uncoated stainless steel, and the overall compressed thickness is .051 inches, with a bore size of 4.200 inches. This construction not only provides a strong seal but also helps the gasket rebound and resist corrosion, making it a solid choice for your engine build.

This gasket fits a wide range of vehicles, including many Chevrolet and GMC trucks and cars from the early to mid-1980s, as well as models like the Avanti II and Checker Marathon. It's a direct replacement designed for a proper fit.
