This issue shouldn't even be an issue accept for want-a-be mechanics who over torque the rocker shaft.
Stay tuned, we've identified the problem and working on two different paths to resolve the issue.
Now for the real world testing.

When you say over-torque, what kind of values are you saying? I remember reading that some amount of torque over spec is recommended for older engines, but I always felt iffy on that.
