Cometic Chevy Gen-1 Small Block 4.100 inch Bore .030 inch MLS Head Gasket (18 or 23 Deg. Heads)

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It features a 4.100 inch bore and a compressed operating thickness of .030 inch, specifically made to work with 18 or 23 degree cylinder heads. These gaskets are built to handle the demands of high-output engines and are suitable for use with both aluminum and cast iron blocks, as well as aluminum heads.

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements. Because they are made of multiple steel layers, these gaskets do not require any additional sealants for installation.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal from the early to mid-1980s. It's a solid option if you're rebuilding the top end of your Gen-1 Small Block Chevy and need a reliable seal.
