Cometic Chevrolet Mark-IV Big Block V8 .120in MLS Cylinder Head Gasket - 4.540in Bore

When you're rebuilding the top end of your Chevrolet Mark-IV Big Block V8, you need a head gasket that can handle the power. This Cometic Multi-Layer Steel (MLS) gasket is designed for just that. It's built with multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps it resist corrosion and maintain a solid seal over time. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes, making it suitable for use with both aluminum and cast iron blocks.

The compressed operating thickness of this gasket is .120 inches, and it features a 4.540-inch bore diameter, making it a good fit for a range of Chevrolet Mark-IV Big Block V8 applications. For example, it fits vehicles like the 1965-1975 Chevrolet Bel Air, the 1967-1972 Chevrolet Camaro, and the 1965-1974 Chevrolet Corvette. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation. This well-built gasket is ideal for high-output engines where reliable sealing is critical.
