Hard to say from the pic. Can you borrow or rent a bore scope for a better look?

A machine shop can re sleeve the lifter bores. I've done this (machine shop) a few times.

I may have answered my own question when I pulled the crank and pistons out. A lifter when came off and partially imbedded itself into the block. The bottom of the lifter bore on the number 3 picture is pretty bad looking.

Should be sleeve able. Could try to hand sand it and then measure the clearance and check it to spec. I do this on over head cam engines all the time. On the cam journal.
