Cometic Chevy Gen-1 Small Block V8 .040in MLS Cylinder Head Gasket - 4.100in Bore - Round Bore

The outer layers of this Cometic head gasket are coated with Viton, a heat-resistant rubber material rated up to 482°F, designed to handle tough sealing jobs. This gasket is built with multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps it resist corrosion and withstand the forces created when mating aluminum heads to cast iron blocks. It has a compressed operating thickness of 0.040 inches and a round bore, making it suitable for a wide range of Chevrolet Gen-1 Small Block V8 engines found in vehicles like the Chevrolet C10, Camaro, and GMC C1500 from the early to mid-1980s.

Cometic's Multi-Layer Steel (MLS) head gaskets are engineered for high-output engines and don't require any additional sealants, simplifying installation. The multiple stainless steel layers provide a solid foundation, while the embossed outer layers with Viton coating ensure a tight seal against various surface finishes and operating conditions. This construction is ideal for applications where aluminum heads are used with either aluminum or cast iron engine blocks.
