Oxalic acid solutions will assist in removing rust buildup, available at most any decent hardware store. It was the active component in the vintage duPont radiator cleaner. Use about 2 cups in 5 gallons of water. Go for an hour drive and let the solution get good and hot. You'll want to use a neutralizer afterwards, something like sodium carbonate. Consider doing a before and after flow rate test on your core.

Yes, it's a significant job to remove the radiator, it must come off with the shell and shutters as an assembly. Really heavy, wrap the headlights with cushioning and rotate them out of the way to prevent accidental damage, it's close quarters. Of course you'll have to remove the hood and the radiator support rods; consider the use of a block and tackle.

Didn't I suggest a while back that if your oil cooler had been blanked off, your problem may be with the internal baffle at the front end of the water jacket plate? I don't recall your ever clarifying that issue.
