Sleeved 59AB Questions

[neilp]

Hi,
In trying to learn all things flathead I decided to tear one down. I found a cheap 59AB and have been happily disassembling it for the past few weeks in my spare time. There was a rebuilder tag on the block and I found that all of the cylinders have been sleeved to 3 3/16" with thin wall 1/16" sleeves. I would like to try to rebuild this block for the experience and end up with a spare engine to use in some future project. I have found no visible cracks in the block and assuming this is the case after testing, What would you do with this block if you just wanted a street engine with a bit more power? Thank you for your feedback.
