Cometic GM Gen-1 Small Block V8 .052in MLX 4.220in Bore Cylinder Head Gasket

Starting with a compressed operating thickness of 0.052 inches, this Cometic MLX head gasket is built for GM Gen-1 Small Block V8 engines with a 4.220-inch bore. It's constructed from multiple embossed layers of stainless steel, with the outer layers featuring a Viton rubber coating for a durable seal. This design incorporates an integrated stopper layer, which helps seal the combustion chamber and improves clamp load around the cylinder without causing bore distortion. This gasket is a solid option for rebuilding the top end of a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Century from the early to mid-1980s.

The MLX technology used in these gaskets is similar to Cometic's standard MLS head gaskets, ensuring robust performance. A key benefit is that these gaskets do not require any sealants, simplifying the installation process. They also do not need to be re-torqued after initial installation, which is a common maintenance task for some other gasket types. This means once they're properly installed, you can generally set them and forget them.
