Okay, here's my experience using those part numbers:

Upper: The Gates 20416 was nearly a perfect fit. I just had to trim the radiator end about 1-1/2 inch.

Lower: Because my water pump and radiator necks are misaligned the 20584 didn't work for me. An upward twist is necessary to rectify the two. I visited the parts store with a wire pattern and ended up with a NAPA 7776 (Gates 21064). Trimming the ends off resulted in a very good fit (see pic). I think an even better hose may be a Gates 20811. Next time.

Bear in mind that my engine position may be different from yours so these numbers might not work for everyone.
