13 lbs-ft to turn the rotating assembly is fine.   Anyway, that 
offset main in the back (front?) is mostly to eliminate that "mystery 
noise" that wasn't evident in all engines (who knows why) and wasn't 
all that obvious to begin with, and actually serves no real useful 
purpose in my humble opinion other than to make Mr and Mrs 
McGillicuddy happy and not ask the salesman "why is that little thump 
noise there sometimes when it idles?"

I've used both bearing sets, those with and without the offset main 
and never noticed any difference either way.   I don't think it 
amounts to a hill of beans.
