Break in cam with new Schumacher ceramic headers?

I've seen chrome headers, some tubes blue, with a brown or green one in the mix caused by a booster tap left open, leaning a cyl and the 1 tube glowed, and always looked funny thereafter.
I've seen cars towed in, "new engine wouldn't run right, - ran it for 20 mins to break in cam, the headers were glowing, but we wanted to break in the cam" .
I haven't used "manifold/shop" exhaust in decades, cuz I am confident the motor will fire and run right away, has waay advanced timing, I monitor exhaust temps, and will recognize an issue right away.
If you're not experienced, - just remember those off-colored tubes, and I suggest fear and common sense, and not inconvenience/laziness be your guide.
Good luck .

As mentioned, keep the bags on the headers as long as possible during build, to protect from handprints, and then wipe tubes of handprints before fireup .
