1985-1998 Harley Davidson Big Twin Evolution Big Bore Head Gasket - Carbon

This carbon composite head gasket is specifically engineered for Big Twin engines, providing a high-performance sealing solution capable of withstanding extreme thermal environments. Constructed from premium carbon-based materials, this gasket offers excellent thermal conductivity and superior recovery properties, ensuring a consistent seal despite the aggressive heat cycles and vibration characteristic of a large-displacement air-cooled V-Twin.

The carbon composition provides a resilient yet compressible interface that conforms to minor surface imperfections on the cylinder head and engine block, effectively preventing combustion leaks and oil migration. As a direct-fit replacement, this gasket is an ideal choice for maintaining structural integrity and original performance standards during top-end maintenance or rebuilds for your Big Twin powertrain.
