Cometic Oldsmobile Gen-2 Rocket V8 .075in MLS Cylinder Head Gasket - 4.125in Bore

You're getting a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Oldsmobile Gen-2 Rocket V8 engines. This gasket has a 4.125-inch bore and a compressed thickness of 0.036 inches, making it a solid choice for rebuilding or upgrading your engine. It's built to handle the demands of higher output engines and fits a wide range of vehicles, including models like the Oldsmobile 98, Buick LeSabre, and Pontiac Grand LeMans from the late 60s through the mid-70s.

This gasket is constructed from multiple layers of stainless steel, which gives it 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 helps ensure a strong seal, even with different block and head materials like aluminum and cast iron, and it means you don't need to use any additional sealants during installation. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.075-inch thickness of this particular gasket.
