Went on our tour without repairing the broken head bolt. Ran the a about 400 miles over 5 days. Very hot in the nineties for 3 days. Ran like a top. No problems. Awaiting delivery from Snyder's of head stud drill out collett and bit, new gasket and stud. Since I may have been running with a broken bolt the last 2 years. I'll wait until I've got plenty of free time before I pull the head. The last time on my other A it was a bit of a chore.
Thanks for all the help and advice.
