Oil cooler if it's clogged. Delete the EGR, Fuel Pressure Regulator Spring/Housing replacement, Thermostat if it's questionable, Replace the coolant with something that's not Ford Gold (See the bazillion other threads on coolant), add a coolant filter, add a fuel pressure gauge, Clean the Turbo...
I think that's about it for a good 'while I have it apart' list.... anyone else?
Turbo oil supply line update, and...depending on the engine year of manufacture, the updated turbo oil drain tube.
Oh and do NOT use the black onyx head gaskets. Cool name, bad gaskets that are popping more and more often. Use the OEM gaskets. Remember that the gaskets were never the issue, it was the stock TTY head bolts that sucked.
When you get your heads off, have them checked at a machine shop capable of machining these heads. Flat/straight and checked for cracking. Rebuild the heads if you got the cash.
If the heads require more than 0.008" be removed to achieve flat, then the head must be replaced.
+1 on the turbo oil lines, I knew I forgot something! Might also want to check all the dummy plugs and such, make sure they're not leaking and stuff. Maybe clean the EGR Valve if it's dirty, even if you're doing a delete, you need to leave it installed and hooked up, and it needs to function, or else you could be put in a limp mode. Also, Take off and hot tank the intake manifold, and clean everything else that might have gunk in it along the intake path. Might as well once it's off, and you're deleting the EGR. Get all that crud out of there, and it'll never come back! Re-route the CCV while you're at it too!
This is turning into a 'what I wish I could do to my truck right now' list I think XD
Don't forget the Rev-X in the full synthetic oil once you re-assemble it to clean and prevent injector problems, Opti-Lube XPD and/or B50 in your fuel, and if you switch to Evans waterless coolant in addition to all of the above we've rattled off, you will officially have the most thoroughly taken care of truck on the forums! :lol:
The "step by step" link in my signature line will get the turbo and intake out of the way.
(also has some part numbers posted that might interest you).
Once you are "in that far" the PDF file I attached might help you out getting the heads off. I have never used that particular file, and I hope I never have to...
