Cometic Oldsmobile Gen-2 Rocket V8 .070in MLS Cylinder Head Gasket - 4.200in Bore

What you get here is a Cometic Multi-Layer Steel (MLS) head gasket designed for Oldsmobile Gen-2 Rocket V8 engines. This gasket has a 4.200-inch bore and a compressed thickness of .070 inches. It's built with multiple embossed layers of stainless steel, and the outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction means it's ready to seal high-output engines without needing any extra sealants.

MLS gaskets are a solid choice for combining aluminum heads with either aluminum or cast iron blocks, as they can handle the different expansion rates and shearing forces between those materials. The multiple stainless steel layers give this gasket increased strength and the ability to rebound, while also resisting corrosion. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the .070-inch compressed thickness you get with this specific gasket. This well-built gasket fits a wide range of vehicles, including models like the Buick LeSabre, Chevrolet Camaro, and Oldsmobile Cutlass Supreme.
