Calling the gray hair engine builders here...
Would any of you be concerned flying a (properly) overhauled IO540 narrowdeck versus a newer wide deck? My intention is to keep standard compression on it, this is not going to be a "run it like you stole it" engine. I acquired a midtime core (narrowdeck) and was thinking of putting new cylinders on it and go through the bottom end for my RV10, but I'm getting some widely differing opinions on the sanity of that approach. To be clear - the engine will be overhauled - not just dusted off and installed.
I know parts are getting harder to find, and more expensive. I'm wondering if I'm doing the equivalent of installing a G430W in this case, at the end of its useful service life.
