Model B Ford Dipper Tray

[Dirttrack]

I have a fully pressurized B engine that is being assembled. The previous owner still has the dipper tray in the oil pan, but there is a 1/2 inch hole drilled in each rod/dipper trough to allow the oil to quickly drain back into the pan. The rods are inserted with the dipper scoops plugged. Do I have to leave the dipper tray in the pan, or since the rods are inserted and pressurized, can I not install the dipper tray? I am using a modified pump for the full pressure oiling.
