16787-99-MLS Cylinder head & base gasket kit. 3-7/8" bore MLS

For high-performance 1999 to 2017 Twin Cam builds with a 3-7/8 inch bore, this James Gaskets kit features Multi-Layer Steel technology. MLS gaskets are the gold standard for high-output engines, consisting of multiple layers of steel riveted together to provide a superior seal that handles heat and pressure better than traditional materials. This kit fits 103-inch engines or 88-inch models bored to 95 inches, excluding Twin Cooled versions. It includes two 0.045-inch MLS head gaskets and the necessary cylinder base o-rings to service one engine. Sold as a kit, it is built for durability under heavy load.
