New 6.0 valve springs for Deranged!!!!

Does a 6.0 keep making power above 5k rpm? Where does it start dropping off? How high will these things actually rev?

They will rev. I have set my sights on 6k. They will make power deppending on if we can get the heads to do a better job.
 
Finally got by the shop last night.

I don't remember, are you upgrading your push rods and do we have someone building aftermarket rockers that aren't 4k?
 
Most likely on the pushrods, and we are stuck with the stamped steel rockers. :doh:
 
I am not 100% sure on it yet, I literally stopped by, took a picture and left. I believe the installed height is 1.8, but I don't remember.
