As I was installing my TTi headers I hopped on the TTi website to see what torque specs were on the flange bolts. In the instuctions I saw an alarming bit. It basically said that I should run cast iron exhaust manifolds or an old pair of headers to break in a new engine because of the mixture problems and other conditions that create enough heat to burn the coating off around the header flange. My headers came with the ceramic coating that was pretty scratched up from storage and shipping. I cleaned and scuffed them and shot them again with ceramic coating.
Is there a way to preserve the coating? Something tells me I should have had these baked at a powder coating outfit before I put them on this engine. The engine is installed and I REALLY don't want to remove it...
I’m listening.

If your breaking in a cam then your probably toast the coating. Roller cam should not be a problem.
The coating needs to go through a couple normal heat and cooling cycles to cure properly.

IF you have plenty of timing in the engine and do not run it with retarded total timing you will not hurt the coating no matter what engine or what cam

Hard to know where your timing and mixture will be on initial startup. You might get lucky and be fine, or you could hurt the coating.
I'm pretty sure all coated headers carry this disclaimer.

You lost me at having the headers "baked at a powder coating outfit". I'm not sure how that would help you since you're trying NOT to overheat the headers in the first place.
To answer your question, YES you will generally trash the bright ceramic coating if you're firing up a new motor that hasn't been tuned properly or if you dyno an engine. Too lean and too rich are BOTH BAD. It's unlikely you'll hurt the flanges but too lean will overheat the coating from the flange to mid primary. Too rich and it will overheat mid primary to collector. The headers below took about a minute or two to discolor when the engine was too lean.
It sounds like you need to take the headers off anyway since the coating arrived damaged. Why would you accept them?

Do you have a temp gun? Although you will have a lot going on at start-up, it might be a good idea to monitor the tube and flange temp. If it starts to go high, just shut it down and give it a chance to cool.
That's not going to help much in that its not calibrated for the bright finish. So you'll be off between 150f and 300f to start. Secondly, by the time you see over 1100f it would be too late to correct it.....
If you refuse to take the headers off your best bet would be to aim some heavy duty shop fans directly at the headers to keep them as cool as possible.

So what is the maximum recommended temp for break-in on a new set of ceramic coated headers?
Master, again and still

Just have a timing light at the ready ... connected and the distributor bolt ready to be loosened as soon as it's running and get the timing to 35* advanced ...Have the mixture screws out 2 turns , breaking in the cam you'll be off the idle circuit anyway and if your gas is 10% ethanol make sure to bump the primary jets up 2 or 3 sizes. .
I don't start an engine for break in unless it has a timing light, vacuum gauge, remote tachometer, and a "real" gauge mounted in the oil sending unit, along with a hand held temp gun, all at the ready installed, along with a large fan, or multiple fans,... to start an engine without any of these things in place is foolish, I want to know at a glance what's going on as the motor is turning 2 grand for the next 15-20 minutes, for the carb(s) settings I usually note the full number of turns for the fuel/air idle screws, and turn them all out 2/3's of their travel (as long as it's not a reverse idle circuit!) for initial start up/break in, and monitor assorted temps of the water, heads, block, intake, exhaust, and vac readings to ensure a happy motor break in period

I fried mine; hookers. Had the timing light ready but the friend I had helping me was too worried about topping off the power steering fluid instead of putting the timing light on it first.  It was too late when he noticed that some of the tubes were glowing red. The timing was way retarded at the start. I guess I should have been the one maning the engine compartment while he worked the key and monitored the gauges. With some of what was mentioned above, I'm sure it might be possible not to fry them though.

On my mopars, I use a starter switch attached to my starter relay and start the car under the hood. Or just use a screwdriver on the starter relay. I usually work by myself.

Man, this is all super great. I'm about to assemble my exhaust. Is it best to break in the engine with open headers or connected to the muffler system or does it matter?
You guys are awesome!

Close the exhausts...It's a lot better when you can also hear everything that's happening...
