Replace rings
Is it possible to leave the heads on and replace the rings through the bottom? My truck uses a lot of oil, close to a quart every 200 miles or so. It has good oil pressure and no noises so I want to pull the pistons out and put new bearings and rings in without taking the heads off as I believe they have been changed recently.

Its not leaking. It's using. Valve cover gaskets are new. Compression is low. I haven't checked it but it can't hold itself on a hill.

I will be doing a compression test this weekend just to confirm, but since it can't hold itself on an incline I'm pretty confident that the compression will be low. I'll also do a leakdown.

You are likely correct, but, having the RIGHT answer to where your compression is going will save you a lot of heartache. And probably a few bucks having to redo stuff as well. The heads on these engines are notorious for cracking around the valve seats, and if run like that long enough, will actually burn away the valve seat.... so, low compression.....
