I got my 3 row radiator by accident, did not order one. I just wanted a generic replacement and that's what I got out of the box. I think it came from Pep Boys.
Going to a 160F thermostat won't help you if you are overheating with a 180. You will be overheating just the same with a 160. Besides if it did work, you would not want to run the engine too cool anyway. It NEEDS to run at a very narrow temperature window.
I too wanted to run the pump faster, but for the life of me I could not find a smaller pulley anywhere.
