dry sump engine oil level

Hello all. I have finally started up my Blackbird engine with Pace/Nova dry sump system. The question I have is what level of oil should be in the engine? With the oil in the remote tank correct, the engine oil level is 12mm ABOVE the max level on the distick. Oil is being returned to the tank via the oil cooler and 1 of the scavenge lines, (I can't see the 1 going to the PRV in the tank) but as quick as it's being pumped out of course it's being pumped back in...which I'm not complaining about..but what governs the level?
Advice would be appreciated. Thanks
