Cometic Oldsmobile Gen-2 Rocket V8 .051in MLS Cylinder Head Gasket - 4.200in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Oldsmobile Gen-2 Rocket V8 engines with a 4.200 inch bore. It has a compressed thickness of 0.051 inches. This gasket is built to handle the demands of high-output engines and fits a wide range of vehicles, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 1980s.

The gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes. This construction means the gasket doesn't require any additional sealants for installation. MLS gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals.
