so i bought some overbore cylinders but haven't received hem yet. i've tried reading topics about deglazing and haven't found any concrete advise/information just a lot of hearsay. i already have an idea but wanted to hear what some of the experienced people have done. if the cylinders are clean with good cross hatch marks, re-plating is not an option. i was just going to use some green scotch pad with WD-40, ATF, or brake cleaner and clean i all out with soap & water then dry with a towel.

The Nikasil (Gilnisil if OEM) plating should not be honed.  If there is still cross hatching and they measure within specs you are good to go.  If worn (doubtful) or failing they need to be replated.  These folk do that service  http://www.mt-llc.com

Well, putting new rings in a cylinder with good hatch marks that hasn't been deglazed isnt the correct thing to do. The cylinder would be basically polished from previous rings and would need to be deglazed for proper seating of the new rings. I'm not wanting to hone at all.

Nikasil is a completely different animal from a steel liner.

You can do as much damage as good by honing because the hone will leave residue in the porous surface of the Nikasil.

Wash it with a solvent to remove any baked on oil residue and put it together.

That's why I was suggesting to just rub the cylinders with fine scotch pad(green) and ATF by hand.  Just to clean everything out. Nothing crazy.

You could...

I'd just clean them with brake cleaner and be done.

I flex hone them to clean them up.  they're so hard that you need to diamond hone them to actually change the surface.
