Oh is this true with a 7.3 as well?? I was always under the impression that the redesigned held bolt system of the 7.3 eliminated the need for re-torque. But i could easily be mistaken.

No, you are right. The 7.3s have bigger head bolts so it's less of a problem. However, the shop foreman said they'd installed quite a few ATS turbo kits at their Ford truck dealership and he said no matter if it was a 7.3 or 6.9 they would NEVER install a turbo without retorqueing and he told me to do the same. This was WAY back in '92 when the 6.9/7.3s were all over the place and people were installing aftermarket turbo kits like crazy. I was a heavy truck diesel mechanic at the time but the small Ford diesels were new to me and I had basically phoned him to get his opinion as to whether or not my pickup would self-destruct if I installed an aftermarket ATS. That was when Ford was big into heavy trucks and the dealer was far away but they had better and quicker heavy truck driveline, engine, etc parts availability for us rather than the local Peterbilt, KW, etc dealers so that's how I ended up picking his brain.
