Cometic MLS head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 3.86-inch bore and .036-inch compressed thickness supplies reliable multi-layer sealing. Embossed stainless-steel outer layers are Viton-coated and the center shim is uncoated stainless steel for thickness tuning. MLS construction needs no sealants, resists corrosion and shearing between different materials, distributes clamp load evenly, and helps reduce bore distortion for consistent sealing performance.
