I've had a few parts saws in the garage for awhile now. Some 066, an 044, and a 440. And a husky 395. I built a nice 066 from the pile with the help of some new parts as well. Today I figured I'd start an 044 project. I knew there was ring or piston failure, which didn't bother me. I've been able to save most cylinders by cleaning off the transfer. This is more of a failure than a scoring.

How high above the port is it?

I didn't measure it, but I'd say .080-.100". Which isn't terrible I guess. It's right in the middle about 3/16" wide. The damage to both cylinders is almost identical. One has a thin gouge up to the top of the exhaust, which might fill in with carbon anyway. The other has a 1/16" spot at the top of the bore where the plating is gone

In pics 2 and 3, you can see what Mustang Mike was talking about in reference to transfer port quality in the gillardoni cylinder vs ks

After you cut the band, open the chamber a bit to lower comp. blend the squish band to chamber edge with a carbide ball and create a bell shape, or just radius on your lathe.

I bet with a squish cut, you may be able to grab 98* outa that sucker.

As you know, the amount you take out of the band isn't linear to the amount you'll need to raise the exhaust.

On a 262XP I did, a .040 band cut and .020 squish correction had me raise the exhaust almost .125 to get to 103*. I was quire suprised, and the saws pulling 240psi.

You can also go with the old T port design as well a pointed roof will lower cranking comp, be easy on rings, and effectively open/close later at rpm.

Raise the exhaust! oops that's already near done.lol I think with a little work that could be made into a nice runner, its injury could have been in far worse places IMO. You could end up with a highly desireable saw owing you not much, good luck with it.
