Flow Bench Valve Wrenches

Save time controlling valve lift during the flowing process with these quick and easy to use flow bench valve wrenches. Each wrench is .100" thick allowing you to flow test cylinder heads at each incremental point quickly without having to readjust and measure your valve depth. What is truly unique with these compared to other methods is that it is extremely versatile and fits almost all cylinder heads.

Stack up however many you want to match your maximum valve lift, then remove one wrench, valve is open .100", remove another and valve is open .200" and so on. Once you use them you'll never go back to your old, slow method of setting the valve lift.
