Exhaust Gaskets BBF 460 Square Port

The Exhaust Gaskets BBF 460 Square Port by REMFLEX EXHAUST GASKETS are designed for big-block Ford applications, specifically for those utilizing the 460 cubic inch engine with square port cylinder heads. These gaskets are essential for anyone building or maintaining high-performance big-block Ford engines, where proper exhaust manifold sealing is crucial for engine longevity and efficiency.

Engineered from graphite-impregnated, high-temperature composite material, REMFLEX gaskets flex with the expansion of the engine block and manifold, providing a significant advantage over rigid metal gaskets. This flexibility allows them to withstand the thermal cycling typical in engine operation, where manifold temperatures can exceed 1200°F. The square port design ensures a perfect fit, preventing bypass leakage and ensuring complete port coverage.

Serious Ford engine builders, whether restoring classic vehicles or enhancing modern performance, will appreciate the durability and reliability of these gaskets. The 0.55-inch thickness ensures optimal compression set retention across numerous heat cycles, while the material's resistance to oil, coolant, and fuel degradation makes it a superior choice compared to conventional composite gaskets.
