Cometic Chevy Gen-1 Small Block V8 .045in MLS Cylinder Head Gasket - 4.200in Bore

Starting with the embossed outer layers coated with Viton, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. The Viton coating is a heat-resistant synthetic rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for the demanding conditions found in high-output engines. This gasket is designed for Chevrolet Gen-1 Small Block V8 engines and features a 4.200-inch bore, with a compressed thickness of 0.036 inches.

The Multi-Layer Steel construction uses multiple layers of stainless steel, which not only increases strength but also allows the gasket to rebound and resist corrosion. This design is particularly beneficial when mating aluminum heads to either aluminum or cast iron blocks, as it can withstand the shearing forces that can occur between dissimilar materials. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045-inch specification on this particular gasket. These gaskets are intended to seal effectively without the need for additional sealants.

This gasket fits a wide range of vehicles, including many Chevrolet C/K series trucks, Camaro, Corvette, and GMC trucks from the 1980s. It's a solid option when you need dependable sealing for your engine rebuild or performance upgrade.
