That's a hard call...
But then again, if you get the engine all back together, as good as new, only to have a missed piece of debris ruin it again.... then not splitting the cases will seem like a stupid thing to avoid....
I know I would resist splitting the cases... but unless I was virtually positive I had all debris, I most likely would...
And I'm not sure I could sleep if I didn't split them, even if I thought I had all the debris...

I just upgraded my cam chest. Part of the items I used was an S&S cam chest bearing set and it came with KOYO rear bearings just like the ones you described. I havent had them in long enough to give an informed opinion but all is running real smooth and you will never have to pick pieces of bearing cages out of the bottom end,

I just went through this (shattered an inner cam bearing on removal) on my M8, I had all the rollers but the cage was too damaged to determine if all the pieces were there.
I never considered not splitting the cases (probably due to so many years in the aviation industry, seeing the effects of foreign objects).
There was nothing inside the engine...but I never regretted doing the extra work.
