What the heck happened?

Sounds like you found your problem. I'd pop the springs off all the valves on that head while it is off and check for no tightness of the remaining guides. I wouldn't worry about the piston.

I just bent an intake valve on my engine last year. I had just replaced the rockers arms and was tapping the engine around with a remote starter button to adjust the pushrods and I heard a slight crack and pop. It turns out I didn't check ALL the pushrods to see if they were seated. One wasn't in the cup of the lifter and actually broke the rim of the lifter and bent an intake valve. After all these years of working on Buick engines and having changed at least a hundred sets of rocker shafts I end up doing something like that. I'm getting old. I'm going to be turning the engine over by hand a couple of revolutions whenever I do something like that from now on.

Double check that your pushrods are seated. Do as I say, not as I do.

Thanks for the advice that sounds like something that easily could have been what happened to me (a first timer).
