Default Bent a pushrod

Yesterday I finally got the MSD box back (they repaired and updated everything under warratny). After installing it and the noise filter I went for a test drive. Everything was fine. Then I picked up the wife to drive her to the body shop to get her van. On the way there the car started making a horrible popping noise. Then she heard a bang and the engine wouldn't idle at all and stalled out. I pulled into a parking lot and restarted the car. Told her to keep it running and opened the hood. The popping almost made me deaf. No more tapping noise though.
I drove the car home and later on took the passenger side valve cover off:





What I think happend is this:
The pushrod adjuster on the exhaust vavel backed out of the rocker(the tapping noise). It fell all of the way out and the exahust valve would not open. ON the next cycle after it would not open the compression in the cylinder kept the intake valve from opening, causing the pushrod to bend and the rocker bolt to snap in the head. the Rocker arm then rotated toward the exahsaust valve and the pushrod was pressing the rocker arm against the valve stem..hence the new dimple in the side of the rocker.

Now I need some contact info for OMEGA PERFORMANCE. They are the ones who manufactured the rocker arms and I need to see about gettting a new rocker bolt. And I also need to see if maybe I got a defective rocker adjuster and how to check that out.
Anyone got any ideas. I knwo a bunch of people are running Omega stuff, but I can't find anything about them on the web.
