I just picked up a set of headers from HPC here in Phoenix, and posed the question to the manager. His feeling is that ceramic coating the outside AND inside of 355 headers would significantly reduce the chances of cracking. He said it's too hard to quote exact temperature numbers, but if before you could hold your hand four inches from the header, you could now hold your hand one inch from the header. Sounds pretty good to me.
I didn't ask about a guarantee - why should he?
