Break in cam with new Schumacher ceramic headers?

I think the conclusion they’ve come to through research is most people have no idea how to set the static ignition timing and get an engine to light right off when breaking in a cam. And most are afraid of rpm when doing so. But that is speculation on my part. I’ve broken in an engine with ceramic coated TTIs ($$$) and they were clean, and the engine was set up properly for break in, and the headers looked brand new years later. YRMV
