The Cometic MLS head gasket for AMC 290/304/343/360 Gen‑2/3 V8 (4.140" bore, .030" compressed thickness) is a multi-layer stainless steel gasket engineered for a robust combustion and coolant seal without sealants. Embossed outer layers are Viton-coated for harsh sealing conditions while an uncoated stainless center shim controls thickness. MLS construction rebounds, resists corrosion and evens load across the sealing area.
