One possibility:

Ive always been paranoid about the mating surface condition between the block and the pickup tube.

If you install an "aftermarket" spacer between the pick up tube and the block then you would introduce another possible leak point.

This spacer has to be "leak proof" on both the block side and the tube side. So, proper surface conditions on all mating surfaces, proper sealer and bolt torque are required to make the joint seal perfectly.

The oil pump is located above the pick up tube flange, and the oil pump would much rather pump air than oil. If the pick up spacer/flange joint is not submerged in oil and not 100% leak proof, the pump might suck air.

Is the flange exposed to air when you turn the car and the oil slosh goes to one side?

Dont know for sure, but its a concern I would have.
