Cometic MLS-5 head gasket for Chevrolet Gen-1 small-block V8 with a 4.060-inch round bore and .070-inch compressed thickness for 18° or 23° heads. Multiple embossed stainless-steel layers feature Viton-coated outer faces and an uncoated center shim for thickness control. This MLS design needs no sealants, resists corrosion and shear between head and block materials, distributes sealing load evenly, and lowers clamp load-related bore distortion.
