About this part

Product Details

This is the Cometic MLX cylinder head gasket, designed for Chevrolet Gen-1 Small Block V8 engines with a 4.220-inch bore. You get one gasket, made with multiple embossed layers of stainless steel. The outer layers have a Viton rubber coating for a good seal, and the compressed thickness is 0.040 inches. This gasket is built to work with All Pro heads and features an integrated stopper layer for sealing the combustion chamber and improving clamp load without distorting the bore.

The MLX technology means you don't need to use any sealants with this gasket, and it also doesn't require a re-torque after installation. This makes for a more straightforward installation process. It's a well-built option for rebuilding or repairing the top end of your engine, offering a solid seal for your Gen-1 Small Block V8.

This gasket fits a wide range of vehicles, including popular models like the Chevrolet C10, Camaro, and Corvette from the 1980s. Always check the fitment guide to confirm compatibility with your specific vehicle.
