thank you bwbenztech

I think your analysis is right on. Hydrolock could've caused a piece of valve or piston crown to shear off. Hopefully the former. This would explain the extreme engine roughness that is occuring if a hole was in either of those and the marks on the spark plug.

BTW. are these pistons hollow?

thanks again
