Cometic MLS head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 4.02-inch bore and .040-inch compressed thickness provides durable multi-layer sealing. Embossed stainless-steel outer layers are coated with Viton and the center shim is uncoated stainless steel to allow thickness variation. MLS construction requires no sealants, resists corrosion and shearing between dissimilar metals, distributes clamp load across the sealing area, and helps limit bore distortion.
