Radiator pipe size?

Hi all, new to this site. I have completely restored two four colunm Rococco radiators that I got off ebay while deployed to Iraqi. Both have been flushed out with phosphoric acid and presure tested up to 60psi. Both of these radiators will be going in my huge hallway which is 13ft high 42ft long and 7ft wide. The rads are 57" long x 11" wide x 38" tall, from what little Ive found on the net they should put out around 24480 btus a peice. These supposedly came from the grand ball room of the Buck Hill Inn in PA before it was shutdown/abandoned. The rads had 1/2" inlets with check valves, My question is, would it be ok to run 3/4 inlets and outlets. Any help would be greatly appreicated. Rich

    Check Out

    The thread to "Old House Guy" and my replies to him as well as the radiation table attachment. 3/4" should be fine, but I've never seen a check valve on a rad.

    The thread is just a couple down from this one.
