Continuation from stuck engine thread< Now what>

[WillC]

If it wasn't for bad luck,,,,, I put the head on and torqued down the very slowly at 10 pounds at a time until it reached 55 pounds of torque. I moved on to install the carburetor. Went to my tool box to grab a wrench and heard this loud bang. At first I thought my shop light fell on the floor, I looked around a couldn't find anything that dropped. Hmm, What the heck was that noise. So back to the carburetor install. I just happen to glance up and seen number 7 head stud laying on top of the block. My heart just about fell out of my chest. It just happened to be the stud that I was unable to get out right in the center of the two bad cylinders. I called every machine shop in my area and no one will pill the broken stud with the engine in the car. This job just went from fun to real work.
