Timing is as good as anything to check first. When you do that also pop the distributor cap off and see if either of the springs are broken or if the little ball in the center of the cap is burned up or broken.

Since the engine had been running great, did Billy say he expected the engine to start to have a decline in performance after a few hundred miles? Or was he just going to tweak it a bit after it was nicely broken in?

When you start the diagnosing, don't take anything apart until you find a clue that the part is misbehaving. It's likely something relatively simple.
