Cometic Ford Duratech 2.3L 89.55mm Bore .040in MLS Head Gasket

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford Duratech 2.3L and Mazda LF/L3 MZR engines. It features a bore size of 89.55mm and a compressed thickness of 0.040 inches. This gasket is built with multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This construction allows it to provide a strong seal without needing additional sealants, making it suitable for engines with aluminum heads and either aluminum or cast iron blocks. The multi-layer design also increases strength and resistance to corrosion.

The stainless steel layers give this gasket the ability to rebound and resist corrosion, while the embossed outer layers coated with Viton are designed to handle demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, with this specific gasket set to a compressed operating thickness of 0.040 inches. This gasket is a solid option for rebuilding the top end of your engine, offering improved sealing performance for higher output applications.
