This is what I'm looking at. The squiggly line on the right is a piece of thread.
Do I need to remove the dark areas that appear to be below the height of the original machining marks?

Do a scratch test on questionable areas to determine staining from foreign material.
I would not be as concerned with that as much as the circumference of the cylinders / cylinder liners. These should be pristine.
P.S - is your crank out? -- why is the #1 piston twisted like that?
Confirm that there has been no impact to that piston (see the outer edge in pic #2) - the edges appear cleaner than the rest of the piston head.
And.. the center of piston head looks abnormal.
