Cometic 75-87 Buick V6 196/231/252 Stage I & II 3.86 inch Bore .080 inch MLS-5 Head Gasket

This is the Cometic C5691-080 Multi-Layer Steel (MLS) head gasket, specifically made for Buick V6 engines with a 3.86-inch bore. It's designed with a compressed thickness of 0.080 inches and fits a wide range of vehicles, including models like the Buick Regal, LeSabre, and Chevrolet Camaro. If you're rebuilding the top end of your Buick V6 or need a reliable replacement for a high-output application, this gasket is built to handle the pressure.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion, which is crucial for long-term sealing. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well with different head and block materials, like aluminum to cast iron. This construction means the gasket seals effectively without needing any additional sealants, making installation more straightforward.
