Ok guys. I'm in the middle of tearing down for my egr delete. I have the intake completely off for cleaning, also goin to do updated HPOP fitting and oil cooler. Just have a couple questions.

1. My intake is off, and it is nasty! But I need some tips on how to go about cleaning around where the intake mounts to block? It's really dirty and I know I dont want all that crap down in there?

2. Where is the oil cooler?? Under the oil filter housing?

3. Where is the STC fitting?

Thanks in advance for the help

Oil cooler directions (literally a step by step) is linked in my signature line. Torque specs, notes, and a bunch of PDF files from the workshop manual.
The STC fitting is located on the HPOP. It is the fitting that attaches the HPOP to the branch tube. When you remove the HPOP, the STC fitting will be attached to it.
The IPR has to be removed, then the HPOP cover comes off, remove the pump. BE CAREFUL in there. Do not get a case of "butterfingers" and drop something. The bolts holding the HPOP are not magnetic and you should remove them by hand after loosening them. The STC fitting replacement kit should have directions with it.

I have attached a PDF file for HPOP removal and replacement.

As far as cleaning the ports on the heads themselves? I didn't touch it cuz I didn't want a big chunk of carbon/soot dropping down where I couldn't get it out with a vac. I just cleaned out the intake manifold with parts cleaner, simple green and a late night visit to the local self-serve carwash (night avoids the bytchin about the crud you will get out of it).

Thanks for all the info NYC. In the PDF for the HPOP it calls for a couple of special tools, for the IPR and the fitting. Do I need these or is it do-able without them?

You can do without those tools, but I do recommend an IPR socket. Check fleabay for one. Should be able to pick one up for about 25-30 bucks.
You can get the IPR out without that socket, but getting it installed with the proper torque is impossible without it
