Intake Gasket Set - SBM

The Intake Gasket Set for Small Block Mopar (SBM) engines is a precision composite gasket pair designed to seal the intake manifold on classic and modern Mopar V8 platforms. Constructed from composite material at 0.06 inches thick, this gasket set addresses the critical seal point between the cylinder head and intake manifold, preventing coolant and vacuum leaks that compromise engine efficiency and reliability. Built to OEM specifications for Small Block Mopar applications, this gasket set delivers the engineered fit required for proper engine function across daily driving and high-performance use.

The rectangular port design measures 1.17 x 2.3 inches, matching the port geometry on Small Block Mopar cylinder heads and intake manifolds. Composite construction provides superior sealing compared to older cork materials while maintaining compatibility with ethanol-blended fuels and modern cooling systems. The 0.06-inch thickness is engineered to compress uniformly under manifold bolt torque, creating a reliable seal without requiring additional shims or corrections. This two-gasket set covers both sides of the manifold interface, eliminating the need for separate ordering and ensuring matched sealing surfaces across your engine.

Technicians restoring or maintaining Small Block Mopar engines—whether 318, 340, or 360 cubic inch variants—rely on proper intake gasket sealing to avoid coolant migration into the combustion chamber and loss of vacuum signal to emission controls. This gasket set is essential for intake manifold removal and reinstallation, manifold-to-head resurfacing projects, and routine engine maintenance. Lightweight at 0.34 pounds, the set ships efficiently and installs quickly with standard manifold hardware. Suitable for factory cast-iron manifolds and modern aluminum aftermarket designs engineered to Small Block Mopar bolt patterns.
