Cometic Oldsmobile Gen-2 Rocket V8 .036in MLS Cylinder Head Gasket - 4.200in Bore

Starting with the embossed outer layers coated with Viton, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output engines. The Viton coating is a heat-resistant rubber material designed to seal effectively in harsh environments and under various load conditions, even on different surface finishes. This gasket is designed for Oldsmobile Gen-2 Rocket V8 engines and features a 4.200-inch bore with a compressed operating thickness of 0.036 inches.

The multi-layer steel construction offers increased strength and the ability to rebound, helping to resist corrosion and withstand the shearing forces that can occur between aluminum and cast iron blocks. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward. This gasket is a solid option for rebuilding the top end of your engine, suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations.

This gasket fits a wide range of vehicles, including many Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models from the 1970s and early 1980s. Always refer to the manufacturer's installation instructions for specific details regarding your application.
