If you crank the nut back till they clatter then tighten them down till they make no noise and they do not oil, then it sounds like the lifter may be plugged. The oil pressure is accurate for a stock pump. The rockers should't make any noise, the quick and easy fix would be to buy a new set of lifters and install them, then you are sure that they are OK. As for the oil holes ligning up I'd say they must be or the cam would seize.
