Cometic Oldsmobile Gen-2 Rocket V8 .080in MLS Cylinder Head Gasket - 4.270in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for Oldsmobile Gen-2 Rocket V8 engines with a 4.270-inch bore. You get one gasket in this package, designed to seal the combustion chamber and coolant passages between your cylinder head and engine block. It's constructed with multiple layers of stainless steel, giving it strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that ensures a solid seal even under demanding conditions, and it doesn't require any additional sealants.

The multi-layer design allows this gasket to handle the stresses between different metals, like aluminum heads and cast iron blocks. The center layer is stainless steel and can be varied in thickness to achieve different compression ratios; this particular gasket has a compressed thickness of .080 inches, resulting in an operating thickness of .036 inches. This gasket is a popular choice for rebuilding high-output engines and fits a wide range of vehicles from the 1970s and early 1980s, including models like the Buick LeSabre, Chevrolet Impala, and Oldsmobile Delta 88.
