I did my bearing roll at 685k, my bearings looked the same as yours. Glad I did them. I did my cam bearings too since I needed a new cam and the bearings were hosed. So far so good. Bought myself enough time to get to an inframe. Next time it gets cam bearings with a bearing roll itll be done with a whole new head.

If you are ever in doubt to do something preventative to your truck, just do it. Im my experience, its better to replace something questionable and know what you have than look back on the side of the road and wish you had. As long as you aren't blindly replacing parts for no reason, anyway. In the last 4 years, I've never had to drive to a dealer with it and she still runs ok, still pulls loads, etc...and Im grateful for that. Take care of it and itll take care of you.

Ive got 24k hours and almost 860k on it now. Doubt it would have lived that long otherwise. Shutting it down after this coronavirus thing settles down for a fresh build.

Yes, torquing the mains per cummins instructions is a PITA...I did mine on my back with a 4' long 3/4" torque wrench. I was sore for days but it was worth it. DEFINITELY helps to have another set of hands but is possible to do yourself, thats for sure. I keep the same wrench in my truck for tire changes.
