The Cometic MLS head gasket for AMC 290/304/343/360 Gen‑2/3 V8 (3.810" bore, .040" compressed thickness) is a multi-layer stainless steel gasket that seals combustion and coolant passages without sealants. Embossed outer layers are Viton-coated for harsh sealing environments while an uncoated stainless shim manages thickness. MLS design rebounds, resists corrosion, and reduces clamp load to limit bore distortion.
