The Cometic MLS cylinder head gasket for AMC 390/401 Gen-3 V8 (4.250 in bore, 0.030 in compressed thickness) provides a multi-layer stainless steel seal with embossed outer faces coated in Viton. Built to handle mixed aluminum and iron mating surfaces, the layered construction rebounds under load, resists corrosion and improves clamp load distribution without requiring sealants for many high-output engine applications.
