BBM 426 Hemi C/P 1.945 Exhaust Valve 5/16

The FERREA BBM 426 Hemi Competition Plus 1.945 Exhaust Valve with 5/16-inch valve stem is a premium exhaust valve engineered for high-performance Mopar 426 Hemi applications. This set of eight stainless steel valves is purpose-built for competition use, delivering the valve seat geometry and material composition required for sustained high-RPM operation and extreme combustion pressures typical of Hemi competition engines.

The 1.945-inch head diameter provides the flow characteristics necessary for maximum breathing in a highly modified 426 Hemi, while the 5/16-inch stem diameter ensures proper seat contact and thermal transfer. At 4.865 inches in total length, these valves are dimensioned to fit the Hemi's specific chamber architecture without modification. The stainless steel construction resists oxidation and corrosion from high-temperature exhaust gas exposure, critical for maintaining valve integrity over repeated competition runs where cylinder head temperatures regularly exceed 900 degrees Fahrenheit.

Competition Plus is FERREA's mid-tier valve offering, bridging the gap between street performance and full race specifications. This line is favored by engine builders preparing Hemi-powered vehicles for drag racing, oval-track competition, and serious hot rod applications where factory valves cannot withstand the demands of nitrous oxide systems, superchargers, or high-boost forced induction. The set of eight covers all exhaust positions in a 426 Hemi configuration.

FERREA valves are OEM-quality components trusted by professional engine builders and high-performance manufacturers worldwide. Verify fitment with your specific cylinder head casting before ordering, as Hemi variants can differ in port configuration and valve seat angle.
