Cometic Oldsmobile Gen-2 Rocket V8 .066in MLS Cylinder Head Gasket - 4.125in Bore

Starting with a .066 inch thickness and a 4.125 inch bore, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious Oldsmobile Gen-2 Rocket V8 engines. MLS gaskets are known for their strength and ability to seal high-output applications without needing extra sealants, making them a solid choice for both aluminum and cast iron blocks. They handle the stress between different metals well.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to work in tough sealing environments and on various surface finishes. The center layer is uncoated stainless steel, and the overall compressed thickness is .036 inches. This well-built gasket fits a wide range of Buick, Cadillac, Chevrolet, GMC, and Oldsmobile vehicles from the early 70s through 1980.
