It sounds like Heli coil time. But, if you are in this situation again, I took my cylinder heads off of my Poly 318 to a shop with an EDM machine when I got two exhast manifold studs broken and stuck. It is a real bastard when you get an easy out broke and stuck. PB and Kroil, although very good, did not work in that case. With the EDM, they can remove all the old metal from around the existing threads one zap at a time and with a tap can clean them up and be reused. It only cost $30.00 in labor, and they had it done in half a day. Just my two bits.
