Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, with a nominal .092 in thickness and a 4.200 in bore. Built from multiple embossed stainless layers with Viton coating on the outer faces and a variable uncoated shim, this MLS gasket rebounds to resist corrosion and withstands shearing between dissimilar materials. It seals aluminum and iron combinations without sealants and helps distribute clamp load to reduce bore distortion.
