Intake Gasket Set - SBF 351C-400M 1.515 x 2.140

The MAHLE ORIGINAL/CLEVITE Intake Gasket Set MS20074 for SBF 351C-400M is a precision-engineered replacement seal designed for serious small-block Ford builders and restorers. Built to OEM specifications, this gasket set addresses intake manifold sealing—one of the most common leak points on classic 351C and 400M platforms. Whether you're running a stock rebuild, a performance upgrade, or a vintage drag application, proper intake gasket integrity is essential for preventing coolant loss, oil seepage, and vacuum leaks that compromise both reliability and tuning.

MAHLE ORIGINAL gaskets are manufactured to exact OE tolerances with a combination of multi-layer steel construction and composite facing materials that resist thermal cycling and chemical degradation. The 1.515 x 2.140 inch port dimensions match the intake runner architecture of the 351C-400M family precisely, ensuring a factory-tight seal without compression or overhang that could restrict flow or cause gasket failure. These gaskets withstand sustained operating temperatures exceeding 200°F and maintain clamping force across repeated heat cycles—critical for both street and competition builds where reliability demands are high.

Technicians rebuilding 351C or 400M short-blocks, swapping manifolds, or diagnosing coolant loss will find this gasket set indispensable for a proper seal. Installation requires manifold removal, surface preparation to 60–80 RMS finish, and torque sequence per factory specs—standard procedure for any serious rebuild. This gasket set is a must-have for anyone looking to ensure optimal performance and reliability in their small-block Ford engine.
