What would you do,???.

I'd sleeve that beeeeeotch in a New York second. I keep the press fit at .0005-.0008 max. That way you don't distort the adjacent bores. Hone the mother and go. A sleeve is cheap money.

BTW, if you brought a block to me that you ridge reamed it would either be bored or I'd hand you my list of other machine shops in the area. I don't put my name on stuff like that. If it had a ridge that needed to be removed, it needs to be bored.
