I know you're relieved! I know the feeling!

Do you trust the threads enough to go back with a stock GM bolt, or do you think you're going with the CAT bolt like I ended up doing?

Probably another ARP bolt, it's slightly longer and (I think) bigger in diameter than the stock bolt. The ARP head bolts certainly seem to engage the threads better. I don't fully trust the threads, but I figure 200 ft-lbs ought to be enough for anyone. And if they do strip, I can always go to the time-sert.

Try pinning the crank, in case you can't get to 200lbs I think you will still be fine running it.
