Cometic Chevrolet Gen-1 Small Block V8 .051in MLS Cylinder Head Gasket - 4.125in Bore

If you're working on a Chevrolet Gen-1 Small Block V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option for sealing your cylinder heads. It's designed with a compressed thickness of .051 inches and a bore size of 4.125 inches, making it suitable for a wide range of applications, including aftermarket heads where customization of water ports might be needed. This gasket fits many vehicles from 1980 to 1986, like the Chevrolet C10, Camaro, and GMC C1500.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, ensuring a reliable seal without needing additional sealants. The center layer is also stainless steel, allowing for different thickness requirements. This construction is ideal for pairing aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals.
