Valve Cover Gasket Set BBM 426 Hemi NHRA

The Valve Cover Gasket Set BBM 426 Hemi NHRA is engineered for serious drag racers and high-performance engine builders running NHRA-legal big-block Mopar combinations. This precision gasket kit seals the valve covers on the legendary 426 cubic-inch Hemi platform, a powerhouse that demands reliable compression sealing under extreme boost, sustained RPM, and violent combustion cycles. Whether you're freshening a stroker build, replacing worn OEM seals, or assembling a show-quality engine, this MAHLE ORIGINAL/CLEVITE gasket set ensures oil containment and prevents fuel contamination at the cylinder head interface.

MAHLE ORIGINAL and CLEVITE are OEM-tier suppliers trusted by factory engine shops and professional race teams for dimensional accuracy and material consistency. This gasket set is designed to handle the thermal cycling, vibration, and detonation loads inherent to supercharged or naturally aspirated 426 Hemi applications running 6,000+ RPM on the strip. The compound used in MAHLE gaskets resists oil degradation, fuel permeation, and coolant weeping—critical factors in a sealed combustion chamber where even microscopic leaks can compromise cylinder pressure and ignition timing. Installation is straightforward: surfaces must be clean and dry, and gaskets should be positioned carefully to avoid edge pinching on the cast-iron valve cover flanges.

This gasket set is ideal for NHRA Stock, Super Stock, and Modified competitors, as well as vintage drag racing enthusiasts and street performance builders who demand OEM-level reliability without compromise. Compatibility is specific to the 426 big-block Hemi platform—verify your engine code and valve cover casting to ensure proper fit. At 0.84 lbs and compact dimensions, the set ships ready to install, requiring only standard hand tools and a gasket scraper. For anyone serious about top-end sealing on a legendary powerplant, MAHLE ORIGINAL valve cover gaskets represent proven durability and peace of mind at the starting line.
