I just completed my 08 4.8i transfer pipe, valley pan, water pump, thermostat, and various hose replacement. I am ready to complete a pressure test. What would be my method for completing the test with the battery disconnected? Fill with distilled water as much as possible and pressure test?

Thats better than no test at all. Air is much more compressible than fluid, so a small leak where you happen to have an air bubble will result in much slower loss of pressure than a fluid leak. But pressure will still drop. Just give the test more time. If it holds, it holds.
