About this part

Product Details

Starting with a compressed operating thickness of 0.060 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. It's specifically designed for Chevrolet Gen-1 Small Block V8 engines and features a 4.100-inch round bore, making it suitable for a wide range of applications including many 1980-1986 Chevrolet and GMC trucks, cars, and Corvettes.

The construction uses multiple layers of stainless steel, which not only increases strength but also allows the gasket to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material capable of handling temperatures up to 482 degrees Fahrenheit. This advanced coating is designed to perform reliably in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, providing a solid foundation for the gasket's structure.

Because these MLS gaskets are well-built and require no additional sealants, they are an excellent choice for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, effectively handling the shearing forces that can occur between different metals. This makes them a solid option for high-output engines where a dependable seal is critical.
