The Cometic MLX head gasket for Ford Duratec 37 (3.845in bore, .042in thickness) incorporates HP shim technology to increase clamp load around the combustion chamber for improved sealing. MLX gaskets utilize an integrated stopper layer for combustion sealing and feature embossed outer layers coated with Viton to meet demanding sealing environments while aiming to control bore distortion under higher clamp loads.
