By this pic I think you need at least one rocker, and I would have a real good look at your cam. Rockers are still available, and Steve aka MCMA from the Yank 600 board might be able to help with a cam if you have the time. They are "Hard faced" so once the wear goes past the hardned part they wear quick.
Keep up the good work!
Edit: looked again maybe it is just the angle of the shine?
