Cometic Chevy Small Block 4.060 inch Bore .023 inch MLS Head Gasket (18 or 23 Deg. Heads)

This Cometic Multi-Layer Steel (MLS) head gasket is built for Chevy Gen-1 Small Block V8 engines. You get one gasket designed for a 4.060 inch bore and compatible with both 18 and 23-degree cylinder heads, featuring a round bore. It's constructed from multiple embossed layers of stainless steel, with the outer layers coated in heat-resistant Viton rubber. This design means it seals tightly without needing additional sealants, making it a solid choice for high-output applications and for use with both aluminum and cast iron blocks.

The MLS construction provides increased strength and the ability to rebound, helping to resist corrosion. The Viton coating on the outer layers can handle temperatures up to 482 degrees Fahrenheit, meeting the demands of harsh sealing environments. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses; this specific gasket has a compressed operating thickness of 0.036 inches and a gasket thickness of 0.023 inches. This gasket fits a wide range of vehicles, including models like the Chevrolet Corvette, GMC C1500, and Avanti II from the early 1980s through the mid-1990s.
