Cometic MLS-5 head gasket for 1975–1987 Buick Stage I/II V6 196/231/252 engines with a 3.86-inch bore and .062-inch compressed thickness supplies robust multi-layer sealing. Embossed stainless-steel outer layers are coated with Viton while an uncoated center shim allows thickness variation. MLS construction requires no sealants, resists corrosion and shearing between head and block materials, distributes load to limit bore distortion, and helps maintain torque set for durable sealing.
