BBM H/P 1.740in Exhaust Valve

The BBM H/P 1.740in Exhaust Valve from FERREA is a precision-engineered replacement valve designed for high-performance Mopar B and RB-series engine builds. This stainless steel exhaust valve serves applications where reliability, thermal stability, and consistent flow characteristics are non-negotiable—from street performance to competition engines requiring OEM-plus durability. Engine builders and performance enthusiasts choose FERREA valves when stock components no longer meet power and longevity demands.

Engineered from premium stainless steel, the BBM H/P 1.740in Exhaust Valve features a 1.740-inch head diameter and 3/8-inch valve stem, measuring 4.910 inches in overall length for direct fitment into Mopar applications. The 5000 series construction provides superior corrosion resistance and heat dissipation compared to cast iron alternatives, critical for sustained boost levels and high RPM operation. Stainless exhaust valves resist oxidation and maintain dimensional stability under extreme combustion temperatures, preserving seal integrity and minimizing blowby across extended service intervals.

This valve is ideal for Mopar B-block and RB-block engine restorers, forced-induction builds, and anyone upgrading from factory iron valves to premium stainless components. Proper installation requires a compatible valve spring and retainer set matched to your specific cam profile and RPM target; consult engine builder specifications before ordering. Individual valve purchase allows selective replacement of worn units or staged head assembly when combining with matched intake valves and supporting hardware for complete valve train optimization.
