Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.02 inch Bore .060 inch MLS-5 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber. The compressed operating thickness is precisely 0.060 inches, and it's designed for a 4.02-inch bore, making it suitable for Buick V6 engines like the 196, 231, and 252 cubic inch displacements found in Stage I and Stage II applications. MLS gaskets are a solid choice for high-output engines because they create a maximum seal without needing additional sealants, and they handle the differences between aluminum and cast iron blocks well.

The strength of these MLS gaskets comes from their layered stainless steel construction, which also helps them rebound and resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit, capable of handling tough sealing jobs and various surface finishes. The center layer is uncoated stainless steel, allowing for adjustments in thickness to meet specific needs. This well-built gasket fits a wide range of vehicles, including models like the Buick Century, LeSabre, and Chevrolet Camaro.
