Yes, I used the Daytona flat face float valves once. They worked fine. The customer was running 2 carbs on a modified engine for vintage circle track racing. He had a bypass type pressure regulator set at 5 lb. All of this was to stop the bowls from running dry at high rpm. The flat face needles were supposed to flow 10% more than stock ones.

At the same time we found that dead head type regulators are unreliable.
