Cometic Chevy Small Block 4.060 inch Bore .084 inch MLS-5 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 with a 4.060 inch bore and designed for 18 or 23 degree cylinder heads. It has a compressed operating thickness of 0.084 inches and features a round bore design. This gasket is constructed from multiple embossed layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit.

The multi-layer steel construction provides increased strength and resistance to corrosion, while the embossed outer layers with Viton coating ensure a reliable seal even under demanding conditions. These MLS gaskets are suitable for use with both aluminum-to-aluminum and aluminum-to-cast iron block configurations, as they can withstand the shearing forces that can occur between different metal types. They are designed to provide maximum sealing performance for high-output engines and do not require additional sealants.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Century from the early to mid-1980s. It's a solid option when rebuilding or refreshing the top end of your small block Chevy.
