Cometic 2014+ Harley-Davidson Twin Cooled 4.250 .066 MLS Head Gasket

If you're rebuilding the top end of your 2014 and newer Harley-Davidson Twin Cooled engine, getting the head gasket seal right is crucial. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these powerful V-twins, ensuring a strong seal between your cylinder head and the engine block.

MLS gaskets are a popular choice for performance and high-compression engines because they offer a more consistent seal compared to older composite designs. They are made from multiple layers of steel, often with a special coating, which allows them to conform to minor imperfections in the mating surfaces while resisting blowout under high pressure and temperature. This particular gasket has a thickness of .066 inches and is designed for a 4.250-inch bore, making it a direct fit for the specified Harley-Davidson models.

When installing, make sure your cylinder head and deck surfaces are perfectly clean and flat. Using the correct torque sequence and values specified by Harley-Davidson is also essential for achieving the best possible seal with this gasket.
