Cometic MLS head gasket for Ford Duratec 25 (2009+) is a .027" multi-layer steel gasket specified for a 90mm bore and uses HP shim technology to increase clamp load around the combustion chamber for improved sealability. The MLS construction combines embossed outer AMP-coated layers with uncoated stainless shim layers for strength and rebound. The embossed outer layers coated with Viton help the gasket conform to varied surface finishes and reduce the need for excessive clamp load.
