Have you confirmed the low pressure, could be just a guage/sender problem. Cam restrictors are an easy fix and perfect for your situation. They have been used on many engines with no ill effects. Still plenty of oil for the cams and valves. Lots of threads on here to read about cam oil restrictors. I don't use them because I have too much pressure when they are installed, but I'd not hesitate to use them if I had low pressure.
