Sb Ford Intake Gasket

The Mr. Gasket Small Block Ford intake gasket is engineered for mechanics and engine builders who demand reliability in high-performance small block applications. Whether you're rebuilding a classic muscle car, tuning a street engine, or refreshing a stock platform, this composite gasket seals the critical interface between your intake manifold and cylinder head. The 0.06-inch thickness strikes the optimal balance between compression ratio preservation and leak prevention—a detail that separates quality gaskets from budget alternatives that compress excessively over time.

Constructed from composite material, this gasket resists fuel and coolant degradation far better than traditional cork or rubber designs, ensuring long-term sealing integrity across repeated thermal cycles. The 1.2 x 2.13 inch rectangular port geometry matches factory small block Ford specs exactly, preventing vacuum leaks that rob power and increase emissions. Composite formulation allows this gasket to maintain clamp load without over-torquing fasteners—a critical advantage when working with aluminum or restored cast-iron heads prone to cracking if over-compressed.

This gasket fits all small block Ford engines from 221 to 351W displacement, making it a must-have for any serious SBF enthusiast. Installation is straightforward: clean mating surfaces thoroughly, position the gasket dry (composite gaskets perform best without sealant), and torque the manifold bolts to factory specification in a crossing pattern. Professionals and DIY builders alike rely on Mr. Gasket's engineering for intake work ranging from routine maintenance to performance builds where sealed air intake paths directly influence horsepower delivery.
