Cometic MLS head gasket for GM 800 Pro Stock V8 (4.755 in bore) is a multi‑layer stainless steel cylinder head gasket with a compressed operating thickness of 0.040 in. Embossed outer layers are coated with Viton to resist heat and harsh sealing environments, while the center shim is uncoated stainless steel for thickness control. The MLS stack rebounds, resists corrosion and evens clamp load across the sealing area to limit bore distortion.
