Product Details

When you're rebuilding the top end of your Harley-Davidson Twin Cam engine, getting the right head gasket is crucial for sealing those cylinders. This Cometic MLS head gasket is specifically sized at .030 inches and features a 3.875 inch bore, designed to work with the Twin Cam platform. It's built to handle the increased pressures and temperatures that come with modern, high-performance engines.

Cometic makes these gaskets in the USA using materials sourced domestically. The Multi-Layer Steel (MLS) construction is known for its durability and ability to conform to the cylinder head and block surfaces, creating a strong seal without needing any additional sealers. This gasket is sold as a pair, so you'll have one for each cylinder when you're putting your engine back together.
