AJ thanks just got home 2 3/4 hours later /sigh I hate i-4.
In a nutshell,
I broke down the kits today, but didnt get the print out of the spring differences between 07 stock and 08 stage2 kit. The 08 kit isnt in the regular 08 catalog /parts book, and no one has the 08 Screaming Eagle Catalog that I know of yet, so I couldnt verify if it was in there or not. the biggest difference seen was the 08 kit uses the 07 rear head, but has a whole new part number for the front head. If you go down to your local harley you will be able to do a complete breakdown on the front and rear heads to find out what springs / valves are in them.
Sorry I ran out of time today and didnt get a chance to get it printed out or write it down, I had to pickup 2 new needle bearings for a buddy and get back.
