Yes.
The only problem you will have with the taller ratios is the bigger diameter pinion will foul inside the bearing retainer.
Simply put the retainer in a lathe and bore it out to clear.

The big cast steel thing (3 or 4 bolts) that holds the mainshaft bearing in... it's behind/around the diff pinion.
It clears a 3.44 pinion, maybe a 3.2, any taller ratio and you'll have to bore it out slightly.
