Exhaust Gasket SBF w/ 1-3/8 x 1-7/16 Sq. Ports

The Exhaust Gasket SBF w/ 1-3/8 x 1-7/16 Sq. Ports from REMFLEX EXHAUST GASKETS is a precision-engineered header and manifold gasket designed specifically for small block Ford applications. This graphite gasket pair seals the critical interface between your exhaust manifold and cylinder head, preventing exhaust leaks that compromise engine efficiency and increase emissions. Whether you're rebuilding a classic Ford engine, restoring a vintage muscle car, or upgrading a performance build, this gasket ensures a reliable, long-lasting seal under high-temperature exhaust conditions.

REMFLEX graphite gasket construction provides superior thermal conductivity and resists gasket creep—the gradual compression failure that occurs under repeated heat cycling. The rectangular port design with 1.375 x 1.437 inch dimensions matches OEM small block Ford port specifications precisely, ensuring proper alignment with both stock and aftermarket manifolds. Graphite material withstands continuous exposure to exhaust temperatures exceeding 1,000°F without degradation, delivering consistent sealing performance across thousands of miles. The gasket pair format allows for immediate installation without additional machining or port matching on most standard applications.

This gasket set is ideal for small block Ford owners tackling exhaust manifold replacement, engine rebuilds, or header installation on vehicles spanning multiple generations of SBF platforms. Installation requires only standard hand tools and basic mechanical knowledge—clean the mating surfaces, position the graphite gaskets, and torque fasteners to specification for a permanent seal. Compatibility extends across most small block Ford engines with rectangular port configurations, making this a trusted solution for both street and performance applications seeking reliable exhaust sealing without premature leakage or costly re-gasket jobs.
