Where to buy coated ARH headers
I doubt people get coated headers for dyno gains. It's mostly to reduce underhood temps and reduce rust on the mild steel headers.

Some people are **** about everything 
I don't think dyno gains are seen because when you dyno a car, you do it with the hood open and fans blasting the engine bay. When you're idling waiting in a staging lane at the track with the hood closed and no airflow cooling the engine, the coating may help by reducing underhood temps (and therefore IAT temps). That's not something you'd see on the dyno because it's a totally different scenario.
You'd have a really hard time proving any gains with that method. The only thing you can do is get an underhood temperature after idling a long time with both coated and uncoated stainless steel headers, then find a way to equate any reduction in IAT temps to horsepower gained. Good luck with that

I am not sure about dissipating heat but SS does not conduct heat as well (almost a 1/3rd) as mild steel according to this chart I found on the Burns Stainless website. To me if SS is not conducting the heat like mild steel then there is less to dissipate.
Yeah i aint smart enough to understand whats going on with that chart so ill just take your word for it.
