Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, specified at a compressed thickness of 0.070 in with a 4.160 in bore. The gasket pairs embossed stainless outer layers coated with Viton and an uncoated shim layer that can be varied for thickness. MLS construction rebounds, resists corrosion and seals without sealants. It handles aluminum-to-aluminum or aluminum-to-iron head/block combinations while requiring less clamp load to help control bore distortion.
