LA vs Magnum rods

IF you have a Magnum engine, with Magnum rods, ARE YOU suggesting that those components need to be turfed for, please explain, what reason?
Just have the LA rods narrowed on the small end. Any competent machine shop can do it. I'm not advocating one is better, as I don't know, I'm simply saying if all you HAVE are the LA rods they can be easily made to work.
