mguner, hadn't even noticed the wear (damage) on the balls?? I don't think they can be reground like the valve tip ends?? I wanted to use adj rockers because I might have the heads cut for better compression (9.2:1). I wanted to be able to get good valve adjustment using the 360 heads and larger valves.
PS - I have the original set of stamped rockers off my 69 318 (still running in the car).
thanks,
Treblig
