Well at least its hot, around 80. Head bolt broken, short one between exhaust port 2 and 3, ideal spot if the must break. It broke in such a way as the top of the broken stud had a hooked slant to it so with a ground grade 8 bolt about 8" long and an impact driver it loosened and I got it out! If I could post pictures I would. Got a new bolt at cummins miami. All is well now but I thought I would pass along my method - no fun.
