My PS VC is pretty close as well. I know I had to cut off the stud portion of the bolts for it to make it fit. I can't recall if I took a grinder and put a bit of a bevel on it or not though. I drove it to work today though, so I'll try to remember to grab some pictures. I did do a cam swap with the engine in the car, so the covers would have come off. They don't really need to lift up if you take the coils off first, they are pretty much flush mount with o-rings, so as long as you can get to the hardware I don't think that would be a problem. I have TTI headers and an older 5.7, but I'll have to look at the DS as well now just because I'm curious.
