Last year I noticed the last bolt in the rear of mine was broken off also. I tried several methods (drilling, easy-out) all to no avail, it really is tight back there to try and get that out. I eventually took the head to a local shop and had them repair. Also had them check the head while it was off.
So my vote would be, have someone else do it. If I had it to do over again, I'd just drive the Jeep to a shop and have them fix it.
