[Spridgets] HD rocker shaft and grub screw location

I'm starting to assemble the rocker shaft for my new 948, and bought a
heavy duty rocker shaft to increase the longevity of the valve train.
Here's the issue, the new shaft has the large hole for the grub screw  in
the #2 pedestal position like the later 1275s do, but my #1 pedestal has
both the grub screw and the oil passage in it.
So, do I drill one of the other pedestals out for the oil passage and move
my old #1 to position 2 (which would be easiest), or do I drill and tap one
of the other pedestals for the grub screw and put a set screw into the
original #1 pedestal?
Either way, modifying the aluminum pedestal is way easier than trying to
drill a larger hole into the hardened shaft.
What say the spridgteers?
