Product Details

The Manley 11892-8 Pro Flo Race Series intake valves are engineered for bracket racing, oval track, and high-performance street engine builds. Constructed from NK-842 stainless steel with a chrome-plated stem and hardened tip, these valves are built to withstand the rigors of high-RPM and high-heat applications.

Each valve features a swirl-polished finish and is fully machined with an undercut stem to maximize airflow into the combustion chamber. The distinctive Pro Flo underhead profile — a 12-degree angle with a 3/8 in. radius — further promotes efficient charge entry and reduces shrouding effects at the seat.
