Your oil pressure is normal for a worn 907. If it doesn't go below 10 lbs you should be fine.
Loss of oil pressure could be related to wear in the main and/ or rod bearings, or wear at the oil pump rotors.

The oil pick-up in the sump may be clogged.

There's a plastic gasket where the oil pump mates to the accessory housing that used to be available in different thicknesses.  There are critical measurements that are described in the manual that determine which thickness to use. This could also affect the pressure.

Or your guage is shot and the oil pressure is OK.
