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

This carbon composite head gasket is specifically engineered for Standard Bore Evolution Big Twin and 1200cc Sportster engines from 1985 to 1998. Constructed from premium carbon-based materials, this gasket is designed to excel in the high-heat environments typical of air-cooled V-Twin engines. It offers excellent thermal conductivity and superior recovery properties, ensuring a consistent and reliable seal through repeated thermal expansion and contraction cycles.

The carbon construction provides a resilient, compressible interface that effectively conforms to minor surface irregularities on the cylinder head and engine block. This ensures a high-integrity barrier against combustion leaks and oil migration. As a direct-fit replacement, this gasket is an ideal choice for riders and mechanics seeking a durable, heat-resistant sealing solution for top-end rebuilds or routine maintenance on classic Evolution and Sportster powertrains.
