First question, when your buddy had the head gaskets replaced did the shop install ARP Headstuds or the Ford OEM headbolts. (Got news for him, if they didn't upgrade to studs he'll be doing that job again eventually). I like to answer the "Bullet-Proofing the 6.0L" question in stages.
Stage One: Get a monitor like an Edge Insight CS/CTS (best cost to benifit out there, but don't buy an older unit, only the CS/CTS can monitor the FICM voltage).
Get the truck out on the interstate and run at 65-70 mph for about 20 mins with that monitor looking at ECT/EOT. If the difference is 15* or better, you'll need to get the oil cooler rebuilt quickly.
Stage Two: (like doing the coolant swap and oil cooler rebuild together to avoid flushing crap into a new cooler.) You'll need the following: Oil Cooler rebuild kit, EGR Cooler Solution (Delete or Upgrade from BPD), all software, Restore, Restore Plus (VC-9), distilled water, and a silicate-free ELC (like CAT EC-1 Rated), and a coolant filter.
-Drain and Flush the coolant with the Restore. (removes the silicate build up from the Ford Gold Coolant)
-Flush with tap water.
-Drain and Flush with Restore Plus/VC-9 (removes rust and scaling)
Flush with tap/distilled water.
-Rebuild your oil cooler (now you have no silicates from the Ford Gold left to clog it up)
-Ensure the oil cooler has the new mesh HPOP filter.
-Install your EGR cooler solution option.
-Clean and Inspect your EGR valve.
-Install your Coolant Filter.
-Fill the system with quality ELC.
Moniter your ECT/EOT to ensure nothing was left to gunk it up, change your coolant filter per manfactors instructions, and every once in a while "Drive it like you stole it" between the EGR valve clogging up with carbon, and the Vanes on your VGT sticking, driving the truck into the high RPM and High Boost conditions every once in a while helps keep the truck running like its suppose to.
Other weak links on this engine:
SCT fitting on the HPOP (was only on the 05-07, doesn't effect your buddy)
Turbo Oil return line (which was the 03-04)
The upgraded fuel pressure unit spring. (all trucks)
Get yourself a quality 4" turbo-back exhaust, an SCT Tuner with custom tuning, and leave the stock intake on the truck and you'll see plenty of reliable power. When you get the SCT, find out what stratagy you're trucks running before you buy tunes. (reference the stratagies on the forums, and see if you want to get the latest reflash before you get tunes written)
If you have to get back in there for gaskets again, get the heads to a machine shop for inspection for warpage and cracking, and inspect your cylinders while you're in there.
You don't need to do the BPD External mounted Oil Cooler. Its a piece of mind vs. nessesity. With the coolant swap and the Ford rebuild kits only around $200, you'll be putting a lot of miles on the truck before making up for that cost.
Also, the 58V FICM (with is made by Swamps) isn't a nessasity.
I hope this helps your buddy, I own and enjoy my 6.0L. Blew gaskets back in January, get it fixed and continue to enjoy the truck. Keep us posted on how it goes.
