You would choose the number to which the magnetic variation is taking
the runway. For example around the western US you would choose the
higher number as if you don't you'll have to renumber the runway that
much sooner.


What??? You don't rename a runway after it has been named.

You most certainly do. Our parallel runways here at BIL were renumbered
from 27 R+L to 28 R+L several years ago. They did this at the same time
they rotated the VOR for the same reason. Another example is MSP. The
parallel runways there were 11/29 until a few years ago when they were
renumbered to 12/30
