If you're trying to do this even partially "right", you shouldn't be letting $100 worth of snap gauges and a caliper stop you. Take your time, do it right. You'll be glad you did.

I do have a caliper and snap gauges, but those are useless to measure cylinder wear. For that you need a bore gauge, and you are right, they are actually much cheaper than I remembered, so I might go ahead and invest into buying one or just take the cases to a machine shop and get them measured. Still, I don`t know the tolerance values for the bore, not even sure if they were released by Porsche.
