Product Details
If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, especially when using All Pro heads, a reliable head gasket is crucial. This Cometic MLX head gasket is designed to provide a strong seal for your engine, ensuring proper combustion chamber sealing and maintaining clamp load around the cylinder without causing distortion.
This gasket features a Multi-Layer Stopper (MLS) design, which includes an integrated stopper layer. This technology helps create a robust seal for the combustion chamber and improves the clamping force around the cylinder. The gasket itself is constructed from multiple embossed stainless steel layers, with the outer layers coated in Viton rubber for added durability and sealing. With a compressed operating thickness of .050 inches and a 4.220-inch bore, it's made to fit specific applications, including those with All Pro heads and a round bore configuration. A notable benefit of this gasket is that it requires no sealants and does not need a re-torque after installation, simplifying the assembly process.
This Cometic gasket fits a wide range of 1980-1986 Chevrolet and GMC vehicles, including popular models like the Chevrolet C10, Camaro, and K5 Blazer, as well as GMC C1500 trucks. It's a well-built option for anyone looking for a dependable head gasket for their Gen-1 Small Block V8 build.
