If you're looking at a 6.0, I'd suggest you stick to 05-07. 03-04 had some issues: improper head bolt torque in 03 on some, a bad batch of injectors from Siemens in 04. In 05, the front suspension was revised: coil springs, tighter turning circle, they ride a lot nicer and turn tighter. After 07, the DPF (diesel particulate filter) was introduced for emissions, and fuel mileage is worse.
Good news: The 6.0 comes with the 5R110 transmission, which is as close to bulletproof as has ever been made. Very rare to hear of any problems with it.
As for reliability of the 6.0 - like a lot of things on the web, it's been blown out of porportion. From what I've seen in the trouble sections here, when someone has HG problems, they usually also have a bunch of performance mods listed in their sig. Adding power has been made real easy - too easy. Plug in a tuner, and crank it up. In an otherwise stock 6.0, that can quickly lead to blown head gaskets, which is a four thousand dollar repair bill. One big difference I've seen between gas and diesel - it's a lot easier to break a diesel when adding power. You can get over 400hp out of a 6.0 reliably, but do your homework first.
My 06 6.0 is pretty much stock, and has been great. Blew a HPOP seal at 94k miles, fixed under warranty. Otherwise, it's been fuel and regular oil changes. Handling, both empty and loaded, is terrific. Hold out for a King Ranch edition if you can, they don't tend to sell for much more, and that saddle leather interior puts a Lincoln to shame.
You do want to change the coolant to ELC, the stock Ford Gold coolant can clog up the EGR and oil coolers if the engine is run hard for long periods of time. That's about the only change you really need to make. You don't need to install head studs ($$$) unless you plan on boosting power. Worth the trouble to do that? Wasn't for me - I bought my F350 to haul loads, and 325hp is plenty for that. If I want to haul a**, I have other vehicles: 1990 Lotus Esprit, 1985 Mercedes 190 Cosworth, 1970 ZR1 Corvette (under extensive restoration right now).
