Fel-Pro Nissan 510 HS 21178 PT-3 PermaTorque Engine Cylinder Head Gasket Set

This Fel-Pro PermaTorque cylinder head gasket set features a steel core, which helps eliminate the need for retorquing head bolts after installation. This is a notable advantage, especially when working on engines like those found in the Nissan 510, 610, 710, and various pickup models from the late 60s through the mid-70s.

Fel-Pro designs these gaskets with the repair environment in mind, meaning they're built to handle imperfect sealing surfaces. They use proprietary materials and unique design features, including a nonstick anti-friction coating. This coating helps seal small surface scratches and imperfections, ensuring a reliable seal for your engine rebuild. The gasket itself often includes graphite or reinforced fiber facing material with steel armor for added strength and durability.

This set is a solid option for anyone rebuilding the top end of a compatible Nissan engine. Always refer to the manufacturer's installation instructions for specific torque sequences and procedures.
