The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 with a 4.375in bore and .051in nominal thickness is a precision sealing solution for big-block engines. Its multi-layer stainless steel construction includes embossed, Viton-coated outer layers and an uncoated shim for thickness control, delivering strength, rebound, and corrosion resistance. MLS gaskets help conform clamp load across the sealing area, reduce bore distortion, and seal aluminum-to-aluminum or aluminum-to-iron interfaces without sealants.
