The only way those pipes are getting cut, is if the coal boiler is going to be removed. If that is so, why do you need to cut the pipes back to the other side of the copper?
Only reason is to have something to thread in to quickly. If it were faster/easier to install pipe caps, I would. The pipe with the coupling won't have to be cut, it will be removed so the bushings can be installed. The other I will cut because I can't turn it out without taking a lot of piping apart to get back from the coupling in that pipe.
I'm pretty sure the seepage will either stop once the boiler is warmed up and the cast iron expands or boiler seal will do the trick, like I said before, I'm preparing just in case the worst happens.
