The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 with Vortec heads (4.165in bore) has a compressed operating thickness of 0.045" and is intended for high-output small-block applications where reliable sealing is required without sealants. Its embossed stainless outer layers are Viton-coated and backed by an uncoated stainless shim, giving corrosion resistance, rebound under load, and improved load distribution to reduce bore distortion across aluminum and iron interfaces.
