You can get rid of the heat shields if you wrap them, which gives easier access to the rear of the engine. Also makes it easier to get them back in.... and out.

Oh that’s an excellent point. I hadn’t thought of that!! That’s what I’ll do. Excellent.
I left them, considering the move as something to reduce heat towards the ICP and IPR. No one has ever shown how much of a heat reduction wrapping would be. It might not do as much as the shields.
I'm not worried about it, but just for the sake of full disclosure - On my last truck (with the same setup) I replaced the up-pipes and ICP at the same time (Feb 2018), and replaced the ICP/pigtail two years and five months later.
Then again, the Feb 2018 ICP was a warranty replacement from 16 months prior, when the stock pipes and shields were intact. And all Motorcraft parts. So who knows. Apparently ICP failures aren't a good metric for measuring temps back there.
Guess I should order a new ICP to have on hand because it seems to be about time.

I didn't think about doing the exhaust wraps until I was about to put the engine back in the truck. The time machine is still broken, so it is hard to go back and get any stock data.
Got the valley all cleaned up and the oil pump out. I was sure someone had been here before because of the loose and missing hardware, but couldn’t prove it. I was hoping to find the STC fitting replaced, but no such luck. I did find out why the heat shield moved around so much. The only bolt in it was the one in the head. There was no screw in the pump housing, and the passenger side tab on the aluminum housing was cut off. I remembered a video from DTR stating that some folks cut this off to make the housing easier to remove with the intake installed. Well, there was definitely the solid proof someone had been here.
So someone was here, but the STC fitting was not upgraded. The work on this ‘05 had to be before 8/08 when I bought the truck. It had to have been a dealer warranty repair based on the timeline.
The cam looks really good from the pump viewing hole.

That same header wrap makes the difference in getting burnt 2 " away at 1200 degrees.
Got the pump put back together, but not without some deep thinking, lol. Maybe someone can confirm my theory. I was certain someone had been in this pump before, since one of the heat shield tabs was cut off the cover. There was a brace that was installed over the STC fitting. My theory is this may have been a recall or tech bulletin to keep that fitting from falling apart. Was this Ford’s fix before the upgraded fitting was available? I think it was because the bolts that were included in the Ford upgrade kit were too short to go through this bracket. I saw a video where DTR mentioned checking the area in the block behind the STC fitting for cracks. Did the STC fitting fly apart with enough force to crack the pump cavity in the block? Did Ford realize this and instruct their mechanics to install this brace?
I looked at several videos and didn’t see anyone remove this bracket on any truck. I certainly didn’t see anyone install an upgraded fitting then install this bracket. I chose to follow the lead of everyone in the videos and remove it completely which enabled me to use the hardware that came with the kit.
International came out with the one-piece fitting upgrade. Ford did not buy into that at first. They decided to go with a cheaper fix ................ ie the bracket. It apparently wasn't as successful as they (Ford) had hoped because it didn't take long to switch to the International fix.

That makes sense except that the bracket also had to be manufactured since it’s a weldment. I guess since Ford didn’t have to take the pump out to install the bracket it would save a few bucks in labor…..but was it really that much? And did the STC fitting really explode with such force it would crack the block?
Yes it can and has come apart with that much force. It is not just my imagination.
The bracket first came out as an alignment tool that came with International's one-piece fitting.
In Ford's early kits (after they gave up on the bracket alone), they gave metal brackets. Soon afterwards though, they went to plastic alignment brackets with the update kits. International kits always had the metal brackets. Was the plastic that much of a savings over the metal - well, obviously it was.
