Cometic MLS head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 3.86-inch bore and .045-inch compressed thickness offers sturdy multi-layer sealing. The embossed stainless-steel outer faces are coated with Viton while the center shim remains uncoated stainless steel for thickness options. MLS construction eliminates the need for sealants, handles dissimilar metal shearing, resists corrosion, and distributes load across the sealing area to minimize bore distortion.
