Yes & no, it depends on the block in question.
Bored quite a few of them to .125 over (481) years ago before I even knew what Sonic testing was.
I also installed a number of sleeves
I would have the block sonic tested as it is pretty inexpensive
It is going to be a little difficult to "bore it to 505" though
