That's a good question. You need some input from CAT. The whole question for them is around if there will be some low end torque loss. With the additional lift and moderate increase in duration, I suspect that the slightly taller gears will be beneficial, but you really need some insight from CAT to help make that choice.
Edit:
I just reread this and realized that I may have the wrong set of cams in mind. Is this the set that pictures and specs were posted for a few weeks ago? The ones that had .266" lift and 270 degress duration (IIRC)? If it a hotter set, you may very well want to stay with the 4.06 gears. Again, you need some input from CAT.
