Cometic Chevrolet Mark-IV Big Block V8 .080in 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 built for those high-output engines. It's designed to seal effectively without needing any extra sealants, making your installation cleaner and more reliable.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and varying surface finishes. The compressed thickness is set at .080 inches, with a 4.540-inch bore, making it suitable for a wide range of Chevrolet vehicles from the 1960s through the 1980s, including models like the C10 Pickup, Impala, and Camaro. These MLS gaskets work well with both aluminum and cast iron blocks, and can handle the stresses between different metal types.
