The Fel‑Pro PermaTorque cylinder head gasket set for Cadillac Seville is a multi-layer replacement engineered to restore a reliable combustion and coolant seal. Designed for repair environments, it compensates for imperfect sealing surfaces while maintaining strength and durability for Seville applications. The set uses graphite or reinforced facing and steel armor with a proprietary nonstick coating, and its steel core helps reduce the need for retorquing head bolts.
