Good catch on the bore... you are correct. Without sending a picture of all the data, variance was from 0.0025 to 0.0035. All cylinders were pretty consistent and no significant "out of round" measurements. I have not measured the ring grove or piston skirt... good thought.
In the past hour, I've been thinking of going ahead and having the cylinders bored 20 over and buy a master rebuild kit that has new everything (pistons, cam, bearings, gaskets, oil pump, etc.) from Engine Tech. Reuse my Crank and rods. Does this sound like wisdom? I STILL have to make a final decision on EFI vs Carburation.

In my opinion, it does, but I am sure there are differing views on this matter. I have re-ringed a coupla engine in the past, with worse wear than you have, and had much less-than-satisfactory outcomes. So anymore, I'll always re-bore. Good bores and good ring seal is a fundamental of a good running engine. And with the kit, you get all the other parts, like a new oil pump, which I always replace. If the truck will be kept for some years, it makes sense to me to do it as good as it can be.
