Both pushrods from one cylinder found off rocker arm

Okay, here's the deal: '01 F250 4x4 with 7.3l. I had a Superchips Performance tune on it and long story short tried to (accidentally of course) drive it down the highway in 2 instead of D.
What caught my attention was when I heard a loud pop and the truck started vibrating as I slowed down. Limped it about 8 mi to the house. It was making a loud noise that sounded like air popping on one cylinder in the cycle. Re tuned it back to stock after which the vibrating and air noises decreased to almost nothing. I took it out for a test drive where I was able to accelerate from a stop up to 70 mph with no major issue.
Today I got both valve covers off and there was one ding mark inside the cover right by the oil fill tube. The very front cylinder on the passenger side had both pushrods off to the side of the rocker arm. The front pushrod is bent to hell but the back one is still straight it was just out from under the rocker arm. When I took the rocker arms off to look around the valve springs i realized the actual rocker arm pedestal was broken at the top where the ball bearing sits.
My concern is what damage could have been done and what else should I look at before replacing parts and putting it back together? Also after calling a couple of local parts stores I'm told they can't get that rocker arm pedestal. Is that available somewhere else or am I going to have to replace the entire head?
