Default Head Bolt Broke Off In Block

It was time to replace the head gasket on the 85 745. Too much oil was accumulating in the cooling system, and the oil leaking to the exterior was creating an enviromental problem. Otherwise the engine was running great, well worth a head gasket change. It is my mileage king, giving a consistent 35 MPG avg. city/highway mix.

One of the head bolts snapped off during removal. #9 in this diagram.

We tried penetrating oil, chisel, propane torch heat, drilling, ez-out. Now want to try the fill-it-with-weld and weld a nut to it method. Since I don't have welding equipment and no experience I will see if a mobile welder can do it.

there isn't anything to weld to. might be better off drilling it all the way out or sending it to a machine shop.
