Ford 352-428 Exhaust 14 Bolt Head 1966-69

The FEL-PRO Ford 352-428 Exhaust 14 Bolt Head Gasket for 1966–69 is a steel core laminate exhaust header gasket designed specifically for Ford FE-series big-block engines. This pair of gaskets features a 1.430 x 2.120 inch rectangular port configuration, engineered to seal the critical junction between the exhaust manifold and cylinder head where combustion pressure and thermal cycling demand absolute reliability. The steel core laminate construction resists blowout under sustained high temperatures and pressure cycling, making it the specification choice for builders and restorers working with classic Ford performance applications.

FEL-PRO's laminate technology layers graphite-impregnated material over a steel core, creating a gasket that maintains sealing force across repeated thermal expansion and contraction cycles. The rectangular port geometry matches the OEM manifold casting profile of 352, 390, 406, 427, and 428 cubic inch FE engines, ensuring precise fit without trimming or modification. At 0.34 pounds per pair, these gaskets meet original equipment specifications while delivering the density and rebound characteristics necessary to prevent exhaust leakage and carbon blowby at the manifold interface.

This gasket set is essential for engine rebuilds, manifold replacement, or restoration work on 1966–1969 Ford vehicles equipped with FE-series powerplants. Whether performing a complete engine overhaul or addressing a failing original gasket, the FEL-PRO specification ensures proper sealing without the degradation that occurs with reused or substandard aftermarket gaskets. The steel core prevents blowout even when manifolds are torqued to specification and thermally cycled through normal operation, a critical consideration for vintage iron that sees regular street or show use.

Restorers and performance enthusiasts restore these FE engines because of their displacement, efficiency, and proven durability. The Ford 352–428 exhaust gasket pair is a foundational component in that restoration process—one that directly impacts combustion sealing, engine longevity, and emissions integrity. Selecting OEM-equivalent FEL-PRO gaskets over economy alternatives ensures the manifold-to-head interface remains sealed throughout the vehicle's service life.
