Very sorry to hear of your drama. It's probably not so much the bolts as the aluminium crankcase threads which won't let you pull the bolts up tight. Then the heating, cooling and vibration take over. Careful you don't strip the threads in the case!!
Perhaps a low to medium strength thread locker will hold the bolts but allow easy removal if needed.
Do you think the valves just needed tappet clearance or do they not seat correctly? I can hear the air hissing out the exhaust port on my ASP 61 when it's on compression, but it does run quite well.
