Cometic 1999 Harley-Davidson Twin Cam 99.5mm Head Gasket

If you're rebuilding the top end of your 1999 Harley-Davidson Twin Cam, a good head gasket is crucial for sealing the combustion chamber. This Cometic gasket is built to ensure a tight seal between the cylinder head and the cylinder block, which is essential for proper engine operation and preventing leaks.

Cometic uses a multi-layer steel (MLS) construction for this gasket, which is a popular choice for performance and stock applications alike. MLS gaskets are known for their ability to conform to the sealing surfaces while maintaining their integrity under high heat and pressure. This particular gasket is sized at 99.5mm, designed to match the bore of your Twin Cam engine. Proper installation is key, so always refer to the manufacturer's instructions to ensure it's seated correctly.
