Yes. The key word here is *MINOR*.

Option 1 is that there's minor pitting on the cylinder walls it can be scraped off by the rings with no ill effect. (This is more likely if you pull the plugs, pre-oil the engine and turn it over by hand until your arms and back ache.)

Option 2 is that the cylinders need to be be rehoned but not overbored and you reuse all the parts.

Option 3 is that the cylinders need to be overbored and you essentially require a top overhaul.

Option 4 is that the engines are severely corroded internally and you need complete overhauls.

Do you have detailed borescope pictures of each cylinder?

Edit: That's why I asked you which airplane it is...we're a very small community and somebody is probably familiar with it.
