Good or bad swap? answer with valad responses please
youre right blockgards will cause your pistons to become oval, which is a greater concern over cylinder wall wear. No engine I ever build will ever have a block guard in it. Block sleeving is not the end all of any of the berfore mentioned issues. Block sleeving causes severe stress to the entire block during and after the sleeving process which can open a whole new can of worms... If I were in your place Id try block posting.
