Cometic MLS-5 head gasket for Chevrolet Gen-1 small-block V8 with a 4.060-inch round bore and .075-inch compressed thickness for 18° or 23° heads. Embossed stainless-steel outer layers are coated with Viton and sit over an uncoated shim layer that can be varied for thickness. MLS construction requires no sealants, tolerates aluminum-to-aluminum or aluminum-to-iron pairings, resists corrosion and shearing, and helps conform load to minimize bore distortion.
