I don't think I want to use my escalade manifold (at least the passengers) cuz its got a massive EGR port I hate, so I'm looking at an LQ4 from an express van for parts that I might use--including the exhaust manifolds.
The full size truck manifolds, and van manifolds are all the same. The early ones had the EGR port machined in, the later ones stil have the EGR bump and hole in the heat shield, but not machined. The Y-pipe cleared everything, admittedly though, it does hang a bit low on 2WD trucks. On my 4x4, it didn't hang below the frame rails. The muffler/tailpipe assembly sits closer to right side frame rail. I actually had a complete 2004 SCSB exhaust system on my 94. I just needed to stretch the tailpipe about 10" and make new hangers to fit it. The current owner of the truck is still running my setup 4 years later with no exhaust issues.
