The Cometic MLS cylinder head gasket for GM/Mercury Marine Big Block V8 Gen-IV/V/VI is a multi-layer steel head gasket that seals high-output engines. This .075" nominal gasket with a 4.530" bore installs with four bolts in the lifter valley and requires no sealants. Embossed stainless outer layers coated with Viton resist corrosion and high loads while an uncoated stainless shim layer enables thickness variation and better distribution of clamp forces across the sealing surface.
