Darton Sleeves.
They're a M.I.D. wet sleeve. IIRC you can go as high as 107mm, and they are iron sleeves, so you can run almost any pistons in them (like uncoated aluminum pistons....).
Not too badly priced, ~$1600-$2000 installed, plus $800-$1200 for a set of over-sized custom pistons, and you can take it up to almost 3.0L all bore....
I have yet to hear of the MID sleeves leaking or shifting under high boost, and they have been used quite a lot.
Some of the dry sleeves are prone to problems. With those scratches, there is no point in re-assembling as-is, because you will have low compression very soon.
