The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 with a 4.375in bore and .036in nominal thickness is a purpose-built sealing component for big-block engines. Multiple embossed stainless steel layers with Viton-coated outer layers and an uncoated center shim provide strength, rebound, and corrosion resistance. The MLS design conforms load across the sealing area, reduces clamp load demands, and seals mixed-material head and block interfaces without the need for sealants.
