1985-1998 Harley Davidson Big Twin & 1200cc Sportster Head Gasket - Teflon

This specialized head gasket is precision-engineered for Standard Bore Evolution Big Twin and 1200cc Sportster engines (1985-1998). Featuring a high-grade Teflon (PTFE) construction, this gasket is designed to provide a superior seal with exceptional chemical and heat resistance. The Teflon coating provides a low-friction surface that allows for the natural thermal expansion and "scrubbing" movement between the cylinder head and the block without compromising the gasket's structural integrity.

Built to endure the intense thermal cycles of air-cooled V-Twin engines, this gasket effectively conforms to microscopic surface irregularities to prevent combustion leaks and oil migration. As a direct-fit replacement, it offers excellent torque retention and durability, making it an ideal choice for riders and builders performing top-end rebuilds or maintenance on classic Evolution and 1200 Sportster powertrains.
