Cutting on a $15,000 Billet Block

Stop,
The sleeves are so damaged on the bottoms( bent and destroyed ) you can NOT pull them up without ruining the aluminum bore.
I know how to remove sleeves, I have done it all, I have a pallet full of replacement sleeves because I made the block to change sleeves at the track with just a puller. Dang.
And sorry I did not wear safety glasses.
