Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, listed at a compressed thickness of 0.030 in with a 4.300 in bore. It combines embossed stainless outer layers coated with Viton and a variable uncoated center shim to meet thickness requirements. MLS construction rebounds and resists corrosion, sealing reliably without sealants. Designed for aluminum-to-aluminum or aluminum-to-iron head/block combinations, it reduces clamp load and helps prevent bore distortion under high-stress conditions.
