I'm with the others as far as the Y being a good design. But you're on the borderline of where I usually recommend changing them out to the earlier T style.
It's not your lift height. That 2.5" would be fine, if you included the dropped pitman arm and trackbar bracket.
For me though, it's the choice of 10" wide wheels and 33's. Will these be 15's still, or will you be going larger diameter wheels too? This can make the difference for me too.
I doubt you'll twist up the linkage from those 33's, just being on the street, but a typical 15x10 wheel can impart a lot of force/leverage all on it's own while driving down the road. So the extra flex of the linkage might make itself known to you in more wandering or slightly more vague steering inputs.
It's not a deal-breaker at this point. I would also normally tell someone to try it and drive it. After all, it's not like you can't easily swap it out at anytime after the fact. A linkage change does not have to be done at the same time as the other stuff.
But you will run afoul of a welded-on trackbar drop bracket needing to be cut back off, or at least modified if you do just the drops first, then change to the T later. That's a negative for doing it later.
So let us know what size wheels, with what backspacing you're planning. The problems start to magnify if you stick with 15 inch wheels that need 3.5" or less backspacing to avoid hitting the tie-rod ends. This negative offset (deep dish) look puts even more leverage against the steering linkage and, again to my mind at least, kind of ruins the good feel that the Y-linkage can have when used with more moderately sized parts.
