new bearings will still vary as much as a .001 new out of the box. that may help you, or it may fuk you over
if your not going to have the rods resized then dont bother with the bearings
I take it you havent rebuilt a 3800 from the ground up before.

Just slapping some new bearings in it without machine shop work on the block will just blow it up.
