Cometic MLS head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 3.86-inch bore and .051-inch compressed thickness provides heavy-duty multi-layer sealing. Embossed outer layers of stainless steel are coated with Viton and use an uncoated center shim to accommodate thickness needs. MLS design requires no sealants, tolerates aluminum-to-aluminum or aluminum-to-iron contacts, resists corrosion and shearing, and helps distribute clamp load to reduce bore distortion for reliable sealing.
