The Fel‑Pro PermaTorque engine gasket set is engineered to provide a superior seal in repair situations, including applications with imperfect sealing surfaces. It combines proprietary sealing technologies, reinforced facing materials and steel armor for strength, a nonstick coating to mask small surface flaws, and a steel core that reduces the need for retorquing head bolts for durable, reliable sealing.
