Cometic Oldsmobile Gen-2 Rocket V8 .080in MLS Cylinder Head Gasket - 4.125in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. This construction is designed to handle the demands of high-output engines, providing maximum sealing performance without needing additional sealants. The Viton coating is heat resistant up to 482 degrees Fahrenheit and is engineered to work well with various block and head material combinations, including aluminum to aluminum or aluminum to cast iron, helping to resist shearing forces.

The center layer of this gasket is uncoated stainless steel, and its thickness can be varied to meet different requirements; in this case, it's set at .080 inches with a compressed operating thickness of .036 inches and a 4.125-inch bore diameter. This makes it a solid option for rebuilding or maintaining engines like the Oldsmobile Gen-2 Rocket V8, as well as fitting a wide range of Buick, Cadillac, Chevrolet, and GMC vehicles from the 1970s and early 1980s.
