The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 engines with a 4.500in bore and .040in nominal thickness provides heavy-duty sealing for big-block applications. Multiple embossed stainless steel layers and Viton-coated outer faces combine strength, rebound, and corrosion resistance. The uncoated center shim can be varied for thickness needs. MLS gaskets seal aluminum-to-aluminum or aluminum-to-iron interfaces and do not require sealants, helping preserve clamp load distribution.
