Cometic MLS head gasket for Ford 429/460 (4.500" bore) is a .040" multi‑layer steel gasket with embossed outer layers coated in Viton for heat and chemical resistance. MLS construction provides improved sealing, reduced clamp load and better load distribution across the sealing area, making it suitable for high‑output engines and mixed aluminum/cast‑iron head‑to‑block applications without additional sealants.
