The Cometic MLS head gasket for Pontiac 400/428/455 V8 (4.410 inch bore) is constructed from embossed stainless steel layers with Viton-coated outer surfaces and a compressed thickness of 0.060 inch. The uncoated stainless center shim provides thickness adjustability. MLS construction seals without sealants, copes with mixed-material head/block pairings, resists corrosion and shearing, and helps conform load distribution to protect bore geometry under clamp load.
