Exhaust Gasket Set SBF 289-351W

The Exhaust Gasket Set SBF 289-351W from REMFLEX EXHAUST GASKETS is engineered for small-block Ford engines requiring reliable header and manifold sealing across the 289 and 351W platforms. This pair of graphite gaskets addresses a critical function in engine assembly: preventing exhaust gas leakage at the manifold-to-head interface, which directly impacts engine efficiency, emissions compliance, and overall performance. For restorers, engine builders, and enthusiasts working on classic Ford powerplants, a quality gasket set is non-negotiable—poor sealing leads to performance loss, heat management issues, and potential carbon buildup.

Constructed from graphite material, the Exhaust Gasket Set SBF 289-351W features square ports measuring 1.438 by 1.625 inches with 3-inch bolt spacing, matching factory head and manifold specifications for small-block Ford applications. Graphite composition offers superior thermal stability compared to conventional cork or fiber gaskets, maintaining gasket integrity across repeated heat cycles while resisting gasket creep and blow-out. The precise port sizing and bolt-hole alignment ensure a leak-free seal without requiring modification to manifold or cylinder head surfaces, reducing installation time and preventing fitment problems during engine assembly or reassembly.

Engine builders, performance shops, and Ford enthusiasts restoring 289 or 351W engines will find this gasket set essential for any manifold removal or engine rebuild. The pair configuration covers both driver-side and passenger-side applications, eliminating the need to purchase multiple kits. Installation is straightforward: position each gasket on the cylinder head exhaust ports, align the manifold, and torque fasteners to factory specifications. This product is compatible with original Ford manifolds, many aftermarket headers designed for small-block Ford square-port applications, and supports both street and competition builds where reliable exhaust sealing is critical.
