Cometic Chevy Small Block 4.060 inch Bore .036 inch MLS Head Gasket (18 or 23 Deg. Heads)

This Cometic head gasket features a multi-layer steel (MLS) construction with a compressed operating thickness of 0.036 inches and a 4.060-inch bore, designed specifically for Chevrolet Gen-1 Small Block V8 engines with 18 or 23-degree cylinder heads. MLS gaskets are a solid choice for high-output engines because their multiple stainless steel layers provide increased strength and the ability to rebound, resisting corrosion and shearing forces, especially when mating aluminum heads to cast iron blocks. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes, ensuring a reliable seal without needing additional sealants. This gasket fits a wide range of GM vehicles from 1980 to 1986, including popular models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks.
