Something In my #5 Cylinder?

Crazy things happen inside these engines and sometimes you get lucky sometimes you don’t. My sons engine broke a 5/16-1/4 inch piece of a stock Edelbrock valve off. (Number 3 cylinder) We did a leak down to find it. We pulled the head and I repaired the head. While he was gone I decided to work on it and don’t ask me why but I climbed under and turned the engine over by hand. The engine suddenly stopped so I turned it the opposite direction and it stopped again. I pulled that head and the valve piece was stuck in number 6 piston. The piece went through the intake to the other side. I dressed it up and reassembled it and ran it three more years of 10 second passes. On rebuild I found it smashed the ring land slightly but not enough to hurt it. We lucked out and I hope you do too.
