I changed my ports because Strange said that one port is timed a little differently than the other. In other words it pressurizes/hits a little sooner. But there is no difference in the pressure.

I do not reccomend you do this unless you know your brake system very good.. Most masters are set up for disc/drum systems and the rear port displaces a greater volume and therefore should go to the front brakes. In my case I have the same brake caliper on all 4 wheels. So the front and back brakes need the same volume. That makes the front port VS the rear port location irrelevent.
