dissassembly of heads on my 01 7.3

I would greatly appreciate some insight on a couple of issues I found today
while tearing down my 01 F250.

this truck was overheated, then it sat for a year before I bought it.
150k miles.
7 out of 8 injector cups pulled out with the injectors.
the gaskets were blown.
Injector and glow plug harness are melted! both of them. is this common?
Driver rear cylinder, #8 has some build up at the top of the cylinder due to coolant getting in it and sitting.
there is no major scaring or pitting on the cylinder walls.
the rest of the cylinders are all uniform in color.
I noticed that the pistons do move side to side quite a bit.
I have not used a dial indicator to measure the amount of movement yet.
im going to estimate about .010"

is this lower end done for?
What should I pay special attention to tomorrow while I clean the block and parts?

I have a fresh set of heads, but I am unsure if I should put them on, or just purchase another block.

much appreciated!

.010 total movement. So .005 all the way around is probably ok. Best way to measure is to check the top ring gap. If the crosshatching is still there its probably fine.

Sounds like PO flushed and refilled the coolant with the wrong type and the retaining compound on the injector cups was compromised.
