You will always have some air escaping the valve cover due to crank case pressure that must be relieved. It is possible that from the engine sump being dry for the rebuild that you are getting a little more pressure developing ? As the piston strokes and back pressures the case it could be coming up through oil ports that have not filled from priming yet ?
Just some thoughts for you.
