The Cometic MLS cylinder head gasket for AMC 390/401 Gen-3 V8 (4.380 in bore, 0.051 in compressed thickness) combines embossed Viton-coated outer layers with an uncoated stainless shim. The multi-layer construction enhances sealing under high loads, rebounds to maintain contact, resists corrosion and helps spread clamp forces to minimize bore distortion in mixed-material head and block pairings.
