My K20 is (I believe) a relatively light-duty truck. Can't recall but it seems like the GVWR was only around 7200#. The OEM front springs were 2-leaf and sagging badly. I measured 7/8" to the bump stops and it bottomed out easily.

I replaced them many years ago with 2.5" Skyjacker Softrides and I'm still very happy with them. I measured 3 3/4" to the bump stops with the Softrides.

Incidentally I am running 255/85-16s (33") on Ford steelies with no clearance issues. Watch your offset and you should be okay without a lift. At most, you might need to lightly trim the lower front corner of the fender.

Thank you for the info, that is very helpful! Ill have to measure the bump stop height but I think I'll be ok to run the 33s I'm looking at. I have also looked into the add-a-leaf option if I need to gain a little bit more clearance. But I will keep the skyjacker soft rides in mind as well. Thanks!
