The Cometic MLS cylinder head gasket for GM LT1/LT4 Gen-2 small block V8 is a .056in multi-layer steel gasket with a 4.040in bore intended for that family of engines. It uses multiple embossed stainless steel layers with Viton-coated outer faces to resist corrosion and rebound under load. The uncoated center shim allows thickness variation while the embossed construction helps conform load distribution, reduce clamp load and minimize bore distortion.
