Mill top surface of block after sleeving

[SuperNovaSS]

Some machinists will use the boring bar to cut down the top of the sleeve flush with the deck surface instead of decking the block.

The decks and the other bores around the sleeves are all warped when the sleeves are put in. The deck needs to be machined and all the other cylinders need to be bored out further. As for saving the numbers,yes it can be done. It usually involves sitting the block sideways on the machine so that the cutter runs across the deck rather than lengthwise. The machinist will center the block so that the number pad doesn't go over the cutter.
