Yes they are both in spec but on the high side. These pressures bleed over from one engine operating condition to the other. It is easier to tune the entire range if starting with the system pressure and warm pressure in the middle of spec. You can then wiggle those adjustments to accommodate your specific engine's needs. If there are other problems causing a rich condition they will only be made worse by a warm pressure that is on the high side.
Without an adjustable WUR this is a moot point though, so swapping out for the known-good '79 is a better option.
