Cory, if I were to try to get out the broken head bolt. I would bolt the head back on and use a transfer punch to find the center of the broken bolt. Then drill a hole down through and apply some PB Blaster. Resist the urgue to use an easy out. They will brake and are VERY nasty to get out. If you have access to a Tig Welder you can weld a nut onto the broken bolt and try with a wrench. Don't wait for the nut to cool down before you try with the wrench though.
