Cometic MLS head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 3.86-inch bore and .030-inch compressed thickness offers multi-layer stainless sealing. The embossed outer layers are coated with Viton and the center shim is uncoated stainless steel for thickness control. MLS gaskets require no sealants, tolerate aluminum-to-aluminum or aluminum-to-iron joins, resist corrosion and shearing, and conform load across the sealing area to help limit bore distortion.
