Details

Manley Race-Flo & Race Master Valves are manufactured of stainless steel XH-426 for the exhausts and NK-842 for the intakes. This series of valves is targeted at the bracket, drag and oval track racers operating below 8,000 rpm.
Any engine builder successfully using EV-8 alloy (21-4N) valves will find a superior valve at a most attractive price.
All stems are hard chromed and hardened tips standard for extended longevity and extra reliability.

Race-Flo valves have reduced diameter stems immediately above the heads for increased air flow which increases power while maintaining reliability.
