Fel-Pro Cadillac Seville HS 8171 PT-4 PermaTorque Engine Cylinder Head Gasket Set

This Fel-Pro PermaTorque head gasket set features a graphite or reinforced fiber facing material with steel armor for strength and durability. It's engineered specifically for the repair environment, meaning it's built to handle imperfect sealing surfaces that you might encounter during an engine rebuild. This is a crucial part for ensuring a good seal between your engine block and cylinder head, preventing leaks of coolant and oil, and maintaining proper compression.

Fel-Pro developed this gasket with proprietary sealing innovations, including a non-stick anti-friction coating that helps seal small scratches and imperfections on the mating surfaces. The steel core design is notable because it helps eliminate the need for retorquing head bolts after installation, which can be a time-consuming step. This set is designed to fit a range of vehicles, including models like the Oldsmobile Cutlass, Cadillac Seville, and GMC Transmode, making it a solid option for many classic GM applications.
