BBM R/F 2.080in Intake Valves

The MANLEY BBM Race Flo 2.080-inch intake valves are precision-engineered components designed for high-performance Mopar B and RB-series engine builds. This set of eight stainless steel intake valves delivers the flow characteristics and durability demanded by serious engine builders and vintage drag racing competitors seeking maximum cylinder head efficiency and repeatability.

Engineered with a 2.080-inch head diameter and 0.372-inch valve stem, these valves optimize air intake velocity and port flow dynamics across the RPM band. The 4.873-inch overall length accommodates standard Mopar B/RB cylinder head applications without modification. Stainless steel construction provides corrosion resistance and thermal stability under sustained high-load conditions typical of competition engine operation. The Race Flo profile is optimized for peak volumetric efficiency, making these valves a direct-fit choice for builders targeting maximum breathing capability in naturally aspirated and forced-induction applications.

This set is engineered for engine builders, restoration shops, and vintage muscle car enthusiasts standardizing on OEM-compatible Mopar architecture. Whether assembling a period-correct 383 stroker, refreshing a 440 Magnum, or building a competition engine for bracket racing, the MANLEY intake valve set provides the flow capacity and material quality required for consistent power delivery and longevity across varying fuel and ignition timing scenarios.

MANLEY's intake valve lineup serves the restoration and performance segment where OEM valve specifications define compatibility and baseline performance. The Race Flo series specifically targets builders seeking upgraded flow characteristics within the Mopar platform ecosystem, where valve head size and stem diameter lock into existing head casting dimensions and valve train geometry.
