Cometic MLS cylinder head gasket for Peugeot XU9J4/XU9J4Z/XU10J2/XU10J4 applications specifies a .054in MLS gasket for an 84mm bore, intended for top‑end rebuilds. The MLS design stacks embossed stainless layers with Viton‑coated outer surfaces and an uncoated stainless shim layer to withstand shear between dissimilar head and block materials. That multi‑layer construction reduces clamp load, improves sealing across varied finishes and resists corrosion without additional sealants.
