On my Excursion project I have my 7.3 with 130k miles. Pulled the oil pan to start swapping out PMR rods for forged rods and found how extremely clean everything looked. Main bearings looked new, rod bearings looked new, cylinder walls all look new. My buddy joked with me and it's true, it sucks tearing apart a perfectly new engine. Anyways, as stated the cylinders all have perfect cross hatching across them. No scoring or anything.

My question is, which flex hone is recommended to use to get the oil glaze off the walls for the new piston rings I'm going to install?

This is a site I came across. Not sure which grit to get.

Unless you are also putting new rins in I would not hone it at all. Just put it back together. Same pistons in the same holes. If you swap holes, put new rings on and hone the holes.

I agree with this. Unless the engine was using oil before it came apart I'd leave it alone. JMO.
