The depth that the belts sit down into the pulleys does not concern me, they look normal. I have had freshly painted pulleys squeal right out of the gate. Paint can be more slick than raw steel. I tend to sand the overspray out of the grooves when putting together a freshly painted pulley. A few motors that I have had really like the belts to be tighter than I'd expect, but once tightened down...no squealing. I often use a piece of broom stick to to get leverage on the alternator when tightening the belt.
