Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.02 inch Bore .040 inch MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically designed for Buick V6 engines with a 4.02 inch bore. You get one gasket in this package, built with multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material, and the compressed thickness is set at .040 inches. These gaskets are made to handle the demands of higher output engines and don't require any additional sealants for installation.

MLS head gaskets are a solid choice because the multiple stainless steel layers offer increased strength and resistance to corrosion. They can also handle the different expansion rates when mating aluminum heads to cast iron blocks, which is common in many vehicles. The Viton coating on the outer layers is designed to seal effectively in tough conditions and on various surface finishes, ensuring a reliable seal.

This gasket is a good option for a wide range of Buick V6 applications, including models like the Buick LeSabre, Regal, and Electra from the 1970s through the early 2000s, as well as some Chevrolet models. It's designed to fit right and perform well without needing extra sealants.
