I searched and found no mention of them (Didn't check the archives though). The information I have shows completely different cam timing than the SVT cams and according to my simulations, they seem to work alot better with our 3.0L than the SVT.
Are they actually different? Any part numbers? Sourcing/pricing?

Yes, they are different. Part numbers all start with 2S7E and they can be identified by their purple color codes versus the old SVT's yellow. I doubt that they are available to dealers in the U.S. I wonder if they are even released for service to dealers in Europe.

They are slightly different. IIRC the SVT exhaust cams were a little more radical than the ST220 exhaust cams, but vice versa for the the intake cams... or was it the other way around.....

Well we can get the ST220 springs (Which oddly list under several of the newer Ford/Mercury/Mazda 3.0s when I search by part number of FPO or Y2KFord), I tried plugging in the 2S7E with the rest of the SVT and non-SVT cam part numbers and nothing came up on Y2KFord.

That's because they are not specifically used for the ST220. It's a common, shared spring between all 2.5/3.0L Duratec. But it's genesis was for increased durability on the ST220 application.
