The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 with a 4.375in bore and .060in nominal thickness is designed for demanding sealing conditions. It features multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim layer for variable thickness control. That MLS construction enhances strength and rebound, resists corrosion, and distributes clamp load across the sealing area to reduce bore distortion while eliminating the need for sealants.
