Sb Ford Ultra Seal

The Mr. Gasket SB Ford Ultra Seal valve cover gasket is engineered for small-block Ford engines, particularly Cleveland and modified applications. This gasket set pairs rubber-coated cork material with 0.187-inch thickness to deliver a reliable seal that balances traditional gasket performance with modern durability. The combination of materials accommodates the thermal cycling and pressure variations typical in street-driven and mildly modified engines while resisting oil seepage that can compromise engine cleanliness and longevity.

Rubber-coated cork remains a proven choice for small-block Ford valve cover applications because it compresses consistently under clamp pressure and accommodates minor surface imperfections on valve cover flanges. The 0.187-inch thickness is purpose-built for Cleveland-series and modified SB Ford blocks where factory gasket specifications call for this exact dimension. This two-piece gasket set ensures complete coverage across both valve covers, eliminating the need to source separate units for left and right sides. Installation requires only hand tools and basic mechanical knowledge—no special equipment or engine removal necessary.

Owners of Cleveland small-blocks, street rods, vintage muscle cars, and lightly modified Ford engines depend on this gasket to prevent chronic oil weeping that can affect spark plug wells, ignition systems, and overall engine bay appearance. Whether addressing a failed original gasket or performing routine maintenance, the SB Ford Ultra Seal provides OEM-level fitment and performance. Mr. Gasket's reputation in the engine sealing market ensures that this product meets the dimensional and material standards expected by Ford engine builders and restoration specialists.
