3.0L SC Oil Pickup Problem

I am getting ready to rebuild my '78 3.0L SC motor for my RSR Clone. The engine will be redone with 3.0L 9.8:1 pistons, 40 mm PMO's and a GE 40 style camshaft. A combo track/street motor.

I am concerned about the oil pickup problem that had plagued some early model 911SC's which were run on the track. I've read that when these early 3.0L motors were run for longer periods at high RPM, that the crankcase would fill with oil eventually draining the tank and causing a loss of pressure. The solution to this problem used to be to add a venturi like pickup to the scavenge pickup (P/N 930.107.314.00).

I would like to use my existing SC style pump for this rebuild. I have the drain sump with the plug in it. Is the current fix still to add the venturi style pickup? Are these still available? Is there a better fix to avoid this problem?
