This Cometic MLS head gasket for Pontiac V8 engines (4.200" bore, .098" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer surfaces for heat and chemical resistance. The multi-layer construction provides strong sealing, reduced clamp load, improved bore distortion control and corrosion resistance, making it suitable for high-output engines without additional sealants.
