Its ashame your on the wrong coast, I could do it for half the price You could buy all the tools needed, even an engine lift and do it cheaper.

 

Maybe his mechanic needs all new tools

 

I noticed it here in the 6.0 section, and it doesn't appear to have been moved!?

A guy who isn't capable, or doesn't have enough time on his hands to do headgaskets on a 6.0, isn't going to be able to do his own cummins swap, and I'd be impressed if you can find a shop that will do it for less than that...
