If they are very close, lets say withing 20% or less of where they should be, then there is no need to change them. Some BED coded resistors were pretty stable, others were junk that have drifted way upward in value, I don't know if this has to do with the manufacturer or with the Wattage they used, some companies, like RCA, liked to cut it pretty close using the lowest Watt rating they could get away with.
