Cometic Chevrolet Gen-1 Small Block V8 .036in MLS Cylinder Head Gasket - 4.200in Bore

If you're working on a Chevrolet Gen-1 Small Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing your cylinders. It's designed with a 4.200-inch bore and a compressed thickness of .036 inches, making it suitable for a wide range of 1980-1986 GM vehicles like the Chevrolet C10, Camaro, and GMC C1500. This gasket is built to handle the demands of higher-output engines, ensuring a reliable seal between your cylinder head and block.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes. This design means you don't need to use any extra sealants, and it works well whether you have aluminum heads on an aluminum block or aluminum heads on a cast iron block. The center shim layer is uncoated stainless steel, and the water ports are undersized to allow for customization when using aftermarket heads.
