Cometic Oldsmobile Gen-2 Rocket V8 .140in MLS Cylinder Head Gasket - 4.200in Bore

If you're rebuilding the top end of your Oldsmobile Gen-2 Rocket V8, getting the cylinder head gaskets right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of high-output engines, ensuring your combustion chambers stay sealed tight. It's designed to work with both aluminum and cast iron blocks, and its construction helps prevent issues from the different expansion rates of these materials.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, meaning you don't need to add any extra sealants. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, like the .140 inch specification on this particular gasket, which has a compressed operating thickness of .098 inches. This well-built gasket fits a wide range of vehicles, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 80s.
