The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 with Vortec heads (4.165in bore) carries a compressed operating thickness of 0.075" and provides a sealant-free multi-layer solution for high-output small-block engines. Its embossed stainless outer layers are coated with Viton and paired with an uncoated stainless shim to resist corrosion, rebound under load, and distribute clamp loads evenly, helping to limit bore distortion across aluminum and iron head/block interfaces.
