An aluminum EQ head would be nice. As to the iron head's pushrod hole.....yeah, it involves machining a much larger round hole, then wedging and sealing an aluminum dowel between the port runner and the intake manifold bolt boss. The whole operation would be much easier on the Indy LAX head where the pushrod hole is enclosed all 360 degrees. In 2010 there was a LAX head part number for an offset pushrod hole. I shoulda bought a few of those heads back then.
