The Cometic MLS head gasket for Pontiac 400/428/455 V8 (4.410 inch bore) is built from embossed stainless steel layers coated with Viton and compressed to 0.040 inch. The uncoated stainless center shim provides thickness flexibility. MLS construction seals without additional sealants, copes with aluminum-to-aluminum or aluminum-to-cast-iron pairings, resists corrosion and shearing, and helps conform load distribution to reduce bore distortion.
