John,
It sounds like you know what you are doing, so I guess it depends on
how you feel about the quality of the old parts. I hope someone can advise
you on that, as I can't. Since the TRF sale is on now, I would buy a
matched set of their pistons and sleeves. This would also cover you if the
old sleeves were a bear to extract (a real possibility, I'm told) and
injured in the process. Good luck with the project.
