The Cometic MLS cylinder head gasket for AMC 390/401 Gen-3 V8 (4.380 in bore, 0.030 in compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim. Its construction resists corrosion and thermal stress, improves clamp load distribution and helps limit bore distortion when used between aluminum and iron mating surfaces in high-output engine applications.
