tryin to break in new engine, ruff idle

Well, with the intake off, I can visually inspect every lobe, and they all look fine. Of course, I suppose it would require a mic measurement on each to be sure. But considering that much slack in those 2 rockers, you'd think I would see something visually on the cam lobes. I looked at them very closely, and can't honestly say I see any wear.

The double springs were recommended by machine shop based on my cam specs. The second spring is not really a full second spring, more of a helper - I forget what they called it...
