It depends.
If the gears whine on accelleration, or decelleration, something is likely wrong.
If they make a slight whine when cruising with your foot lightly on the gas, it is somewhat typical for a performance gearset. Especially richmonds.

Mine make a slight whine at 50-65ish mph with very light throttle. It will sometimes get better with some miles. If it is really loud, I'd take it back.

If the rear gear set up is wrong, it is already too late. The damage is likely done. If putting miles on the car improves the noise, you may be fine. If it gets worse with miles, then the gearset is ruined.
If set wrong, and then reset at a different pinion depth, they rarely survive the 2md break in period.
These statements are not fact, but my opinion based on previous experience.

Two weeks??? What did he do? Remove the diff and send it out to a gear man, as you could have done?

RACE ON!!!

My 3.54 D36 Richmond gears whined like a lonely puppy from the day they were installed, and the whining only got louder. OTOH, they lasted 3 years and hundreds of passes down the track - before they self-destructed.
