Engine Bor options / Sleeve

I have a 73 340 block i bought complete. It is at the machine shop and when i got it 1 of the cylinders had water sitting in it for a while. The cylinder was at std bore it is now bored all the way to .40 over. There are still very little pits in the cylinder wall. Should I go ahead and sleeve it? What are some of the pros and cons to sleeving? How long should it last?

Thanks for the help.
