with this cleaning and devarnishing of parts, might have to run a higher weight oil due to loosening of clearances...

I'm even more paranoid than that...I'd chase the solvent with oil, change oil, run to operating temp, change oil again, then one more time after a couple hundred miles.
Using cheap oil, of course, until I put the oil that was gonna stay in there.
I always worry about that stuff ruining the treatment on the paper element in the filters and making it come apart or hog up...
