The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 with Vortec heads (4.060in bore) is specified with a compressed thickness of 0.036" and designed to seal without additional sealants for demanding small-block applications. Its construction pairs embossed stainless outer layers coated with Viton and an uncoated stainless shim to provide corrosion resistance, rebound under load, and even clamp-load distribution to help minimize bore distortion between aluminum and cast-iron interfaces.
