The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 with a 4.375in bore and .035in nominal thickness provides durable sealing for high-output engines. It combines multiple embossed stainless steel layers and Viton-coated outer faces with an uncoated shim layer to resist corrosion and rebound under load. MLS construction helps distribute clamp force evenly, reduces required clamp load and bore distortion, and seals aluminum-to-aluminum or aluminum-to-iron interfaces without sealants.
