I put the head back on my car today, and when I took it out for its first drive in a few weeks, it seems that one of the exhaust manifold studs came out. I suppose I forgot to tighten it when putting everything back together. My plan is to just go to the hardware store and put a bolt in for now until the new stud and nut make it to my house. What size bolt should I get?

Those are regular M8 threads. Holding my fingers up, the stud needs to be about 1.75" long. M8 studs can be found a decent hardware stores. Get a few different sizes. The problem is getting one long enough but still where the un-threaded middle doesn't stick out too far. (M8 nut and agood washer, too)
In the PET they're listed as an M8x30 but a 30mm long stud is too short and not going to work. (I found this out on my 928) I don't know what the 30mm refers to. Maybe the length of the longer thread?
