Mopar 354-392 Hemi Intake Gasket

The Mopar 354-392 Hemi Intake Gasket is a precision-engineered composite sealing solution designed for early Hemi engine builds and restorations. Built to factory Mopar specifications, this intake manifold gasket prevents coolant and fuel mixture leakage at the critical interface between intake manifold and cylinder head. Whether you're rebuilding a classic 354 or 392 cubic-inch Hemi powerplant or restoring a vintage Mopar muscle car, a proper intake gasket seal is non-negotiable for reliable operation and fuel economy.

Manufactured from composite material at 0.062 inches thick, this gasket features 1.5 x 2.05 inch rectangular port openings optimized for early Hemi intake geometry. The composite construction provides superior resilience compared to paper gaskets, resisting thermal cycling, oil saturation, and coolant degradation that plague vintage engines. The gasket set ships as a pair, ensuring you have matched components for both cylinder banks—critical for even sealing pressure and preventing cross-leak conditions that compromise combustion and cooling flow. Proper installation with factory torque specifications ensures the gasket compresses uniformly across the combustion chamber and intake runner junctions.

Mechanics and enthusiasts restoring Mopar early Hemis—including 354, 392, and related big-block variants—rely on OEM-spec gaskets to maintain factory reliability and resale value. Installation requires careful manifold cleaning, proper bolt sequencing, and adherence to manufacturer torque specifications to avoid warping. This gasket integrates seamlessly into stock or mildly modified intake manifolds and pairs with original Mopar cylinder heads, water passages, and fuel rails. For any serious Hemi rebuild where air-tight sealing prevents misfires, overheating, and long-term reliability issues, the Mopar 354-392 Hemi Intake Gasket is the correct choice.
