Patriot Exhaust 66014 Seal-4-Good Small Block Ford Square-Port Header Gaskets

Patriot Exhaust Seal-4-Good header gaskets are designed to provide a dependable seal between the exhaust headers or manifolds and cylinder heads on compatible Small Block Ford applications. Part number 66014 features a rectangular exhaust port design that helps support proper alignment and sealing for square-port header configurations, reducing the risk of exhaust leaks and maintaining efficient exhaust flow.
Constructed from multi-layered aluminum, these gaskets are engineered for durability in the demanding heat and pressure conditions found in exhaust systems. The layered design helps the gasket conform to mating surfaces while providing a reliable barrier against escaping exhaust gases. This makes the Patriot Exhaust 66014 a practical replacement or installation choice for street, performance, and restoration builds using compatible Small Block Ford components.
Supplied as a pair, these Seal-4-Good gaskets offer convenient coverage for both sides of a V-type engine. Verify header design, cylinder-head compatibility, and fastener alignment before installation. Proper surface preparation and correct torque procedures are recommended to achieve the best possible seal and long-term performance. With its purpose-built rectangular port profile and durable aluminum construction, this gasket set is suited for builders seeking a clean, reliable header-to-head connection.
