Cometic Chevy Small Block 4.060 inch Bore .040 inch MLS Head Gasket (18 or 23 Deg. Heads)

If you're working on a Chevrolet Gen-1 Small Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of a high-output engine. It's designed with a 4.060 inch bore and a compressed thickness of .051 inch, making it suitable for engines with 18 or 23-degree cylinder heads and a round bore design. 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.

Cometic's MLS design uses 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 without needing additional sealants. This construction is ideal for mating aluminum heads to either aluminum or cast iron blocks, as it can withstand the stresses that can occur between different metals.
