The Cometic MLS head gasket for Pontiac 400/428/455 V8 (4.410 inch bore) uses embossed stainless steel layers with Viton-coated outer surfaces and a compressed thickness of 0.036 inch. An uncoated stainless center shim allows tailored thickness choices. MLS design seals reliably without sealants, withstands mixed-metal head/block interfaces, resists corrosion, rebounds under load, and distributes clamp force to limit bore distortion in demanding applications.
