How you keep from dis-coloring your new headers (heat)

[Chlngrcrzy]

I am wanting to buy a new set of tti headers, for my newly rebuilt 440 engine that i have not fired up yet. It is not installed in the car, and i want to be able to install the headers on the motor before i install in car. I understand that there will be some major heat as i run the engine through its break in cycle.  i really dont want to pull the engine afterwards and change to new headers. (i do have an old beat up set of cast iron exhaust manifolds that may or may not fit) What would you all do? i am i worrying too much about it? i am not overly particular, but tti said they would void the warranty, which i am not sure is a big deal anyway. I thought about buying their mild steel headers and just painting them up with some good heat resistant black.

I ran my TTIs for break in. They are still the same colour as when they were new.

If you adjust the timing as soon as it fires up & is up to speed & make sure it is not running lean I doubt you will hurt the headers , I have seen the headers glow orange with the timing off & the mix lean . I go through a system on fire ups & adjust timing & idle speed immediatly , then get on the mixture screws , if it is lean adding fuel with the mix screws will help compensating the jetting if it is off .
