If they were driving it with the valves out that bad, one or more might be burnt... Thats how my current engine is going out. I went on a 2500 mile trip and she started running rough half way there, I thought it was a batch of bad fuel since 2 bottles of diesel 911 helped. But by the next time I stopped, about 500-600 miles later, it sounded like you described. Compression in cyl #1 went from 400 when I bought the engine to 200 after that trip.
