one had a starter motor problem!

-Number 4 piston cam out and broke the starter motor
The other snapped a crank and number 4 rod came through the block.
I had ideas of sectioning the block so I could see the valve to piston clearance when rotating the crank with the head on or if someone needed a dummy block se setup in there engine bay while welding or making brackets?
or I will be throwing them out in the next few weeks.
