I think you are onto the mark with the valve spring. One thing I did not mention is the car ran, but poorly, after it lost all power during a run. I started it maybe five or six times with no power and no expensive engine noise. But the last time I started it, it made all kinds of expensive engine noise.

So, if the valve spring failed partially maybe the valve would not hit the piston but if it later failed completely then it would and that would cause the damage chain to start.

Headed out to the garage in a few minutes will know more tonight hopefully.
