Sinister is also good, mine is a knock off brand identical to sinister's. It's not too bad a job to do, soak turbo bolts, and up pipe bolts with either wd40 or your favorite lubricant to break the bolts loose, a member on here posted a cool home brew for 50% automatic transmission fluid, and 50% acetone in a spray bottle. It beat wd40 in a test measuring break away torque required to loosen a bolt. Just a thought. I didn't spray nothin on mine, and they came right out.
I'd also say that you should look into a coolant filter, and a switch to elc coolant (rotella ultra elc). I did all that as the same time as my egr delete. You flush it all out with restore, and restore plus as directed, and then tons I'd distilled water, then add elc. I have the sinister coolant filter kit. It was like $130 bucks or so, and helps prevent future oil cooler issues. The general concensus is that ford gold coolant breaks down over the high heat of the eve cooler, and in turn leaves deposits in the oil cooler that can clog it, leading to high temp differences between oil and coolant. If I'm repeating stuff you already know, i appologize, but it could well save you time and money down the road.
