You say, "The engine has less than 500 miles since rebuild." The very first step after the engine is tore down for a rebuild should be a soak in a chemical hot tank which not only degreases the block but will rid the oil and water passages of all the rust and crud. Also the rebuilder should have rodded out all of these passages. This rebuilder sounds like he skipped this step. If this was done only 500 miles ago I'd go back to the rebuilder and ask why this was not done and what he is going to do about it.
