Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, specified at a compressed thickness of 0.027 in with a 4.300 in bore. The gasket uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim layer that can be varied to fit thickness needs. MLS construction provides rebound and corrosion resistance, seals without sealants, and is suitable for aluminum-to-aluminum or aluminum-to-iron head/block pairings while lowering clamp load and minimizing bore distortion.
