Cometic Ford 302/351W Windsor 106.68mm Bore .040in MLS Cylinder Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed thickness of 0.040 inches and features a 106.68mm (4.200 inch) bore, making it a solid choice for Ford 302 and 351 Windsor V8 engines. These gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion and withstand the forces generated in high-output engines. The outer layers are coated with Viton, a heat-resistant rubber material capable of handling demanding sealing environments and various surface finishes, ensuring a reliable seal without the need for additional sealants.

The multi-layer design is ideal for applications using aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals. The center layer is uncoated stainless steel, allowing for variations in thickness to meet specific engine requirements. This construction makes them a popular choice for rebuilding or modifying these classic Ford V8s, offering improved sealing performance for engines that push beyond stock power levels.
