Cometic Oldsmobile Gen-2 Rocket V8 .084in MLS Cylinder Head Gasket - 4.270in Bore

Starting with a compressed thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. It uses multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle temperatures up to 482°F. This construction means the gasket can handle the demands of high-output engines and is designed to work well with both aluminum and cast iron blocks, resisting the shearing forces that can occur between different metals.

The center layer of stainless steel can be varied to achieve different thicknesses, and in this case, the gasket has a bore size of 4.270 inches and a compressed thickness of 0.084 inches. Because it's an MLS gasket with Viton coating, it doesn't require any additional sealants, making installation more straightforward. This gasket is a solid option for a wide range of GM vehicles from the 1970s and early 1980s, including models like the Oldsmobile 98, Buick Electra, and Chevrolet Caprice, when you need a reliable seal for your Gen-2 Rocket V8 engine.
