Quietest gears? Yukon? Strange? Motive? Richmond?

I've got a noisy set of 3.91 gears in a clutch 742 center. The gears are a unknown brand that came with my demon, they were loose and not in a box or anything. They were set up by a guy who was recommended as a good rear end guy. I'm wondering if I should take a crack at readjusting them and see if they will be quiet I only put about 1k miles on them , I do remember the pinion being hard to turn when I installed it! Is it true if they were not set up properly and are noisy they will always be noisy???
