Cometic MLS-5 head gasket for Chevrolet Gen-1 small-block V8 engines with a 4.060-inch round bore and .066-inch compressed thickness for 18° or 23° heads. The gasket combines multiple embossed stainless-steel layers with Viton-coated outer faces and an uncoated shim layer to meet thickness needs. MLS construction eliminates sealants, tolerates aluminum-to-aluminum or aluminum-to-iron mating surfaces, resists corrosion and shearing, and helps conform load to reduce bore distortion.
