Don't think a 12.50 will fit so figuring a 305/55r20 would be the biggest I could fit ...though about a 295/60r20 would be near a 34 x11.50. Thank you to everyone who has helped and have advice btw

The bars should still be straight, but over time they are a spring and will loose some of their original spring rate and won’t be able to be cranked as high.
But you won’t be able to level it with keys if there is a 2 inch block on the back, that’s not stock. And with the keys cranked all the way up, you’re going to see faster suspension and cv shaft wear. Also, if you post some pictures it would be easier to tell what exactly is going on with your rig.
A 305/55/20 specs near the exact same dimensions as a 33x12.5r20. It all comes down to your wheel’s backspacing. A wheel with less backspacing will be more likely to rub when turned. If your wheels are stock 20” GMC wheels your backspacing should be fine, but pics would help. I personally run 255/85r16s (~33x10)on 16x6.5 w/ 4.5” backspacing on my 2004 Burb and I’m only about 1.5” higher than stock. They would’ve likely fit at stock height as well, but I wanted the mild gain in ground clearance.
