Thanks Chris,

What would be some indicators/symptoms of an improperly broken in cam?

Well, the cam companies do everything possible to make sure that you don't
have problems, but things can happen. The worst case scenario is that a
lifter lobe will go flat. On rare occasion this can be caused by a soft cam
core, but usually it is insufficient lube at startup. Cam problems really
don't happen as much these days due to improved lubricants and cam
manufacturing processes.

You probably won't notice anything right away, but if an intake lobe goes
flat, you'll lose some power and eventually develop a miss similar to a bad
plug or wire. If an exhaust lobe goes flat you'll get popping and backfiring
through the carb/throttle body. This is because the exhaust will try to exit
back through the intake manifold when the intake valve opens. Unfortunately
I found this out the hard way when I had my first cam go bad and lost two
exhaust lobes on it. This happened after 8000 miles, so it did take a while.
