The Cometic MLS cylinder head gasket, .056" compressed thickness with a 4.200" bore, is specified for W2 heads and Chrysler R3 race block use. Its three- to five-layer stainless steel construction with Viton-coated outer layers resists corrosion and meets harsh sealing demands. The uncoated center shim accommodates thickness variation, while the embossed layers help distribute load across the sealing area and reduce bore distortion under clamp.
