I don't know why I got a bad rap here, for recommending the right way to do something.
If you guys bought a brand new engine from me, would you want me to just go find a 35k mile core, roll some new bearings in it, run a ball hone down through the cylinders, wipe the cylinders down with paper towels, and throw a set of heads on it?
I understand that this is supposed to be a freshen-up, but the same underlying key components still apply here. Are the cylinders going to have ridge in them? Maybe, maybe not. Are the cylinders going to be straight? Maybe, maybe not. If you roll new bearings in, are they going to have the same bearing clearances as before? Maybe, maybe not.
I apologize if I came across too crass....but I'm a stickler for perfection. And in my eyes, if you're going to take an engine down to the point that you're going to take it down to, you might as well check everything else out and learn some more "stuff."
