Bryan,
I would suggest taking pressure measurements before tearing the installation apart. The data will help determine the problem source, heat generation vs. heat dissipation.
CHTs are primarily driven by EGTs (mixture) and cooling air flow. The differential pressure test will verify air flow. Since CHTs in cruise are good and reported fuel flow in the climb sounds low I would suspect the carb itself.
I wouldn't expect any global CHT change by moving the oil cooler, since the source of air and the volume extracted will be roughly the same.
I do like switching to a larger cooler. If I recall, you had some kind of space constraint that made it difficult to put the larger cooler in the same location up front.

I'm starting with the changing of oil cooler to a larger one and relocation to engine bay with scat ducting to it off the baffling.
If that doesn't do it I will move on to the next idea.
My hopes are that my oil comes down and helps the cht's too. I also hope that closing off the large hole in the front baffling from old oil cooler placment helps with cht's
