is this alright to do this to my headers

What exactly will your headers be coated with? What is "heat treated paint"? You need a cera-metallic (e.g. - JetHot, Airborne, etc.) coating. It will reduce heat loss through the tubes, increasing performance, reduce underhood temperatures, and reduce corrosion and stress cracking. There is no "paint" that will provide those benefits. If you have the cera-metallic coating, you don't need a wrap.
Wrapping headers increases the rate of corrosion due to the extreme tube metal temperatures, increases cracking at the welds, and may increase the risk of fire.

The wrap increases the rate of tube metal oxidation (= rust) because it holds the mild steel at such a high temperature (virtually equal to EGT), the iron starts to combine with the oxygen in the air.

No.... they don't hold in moisture. How could a piece of fabric operating at 1,000*F contain moisture?

Ive always heard they held in moisture though, like if it gets hot then cold, wouldnt you get condensation between the metal and the wrap?
Kinda like if you go outside and its 80 degrees, you shoot your rifle and few times and put it in your car with the a/c on. the gun starts to "sweat"

Since the wrap is holding the tube metal temps above the ambient air temp for a period, when you shut the engine down, it not likley that they will suddenly sub-cool below the dew point, allowing moisture in the air to condense out. Trust me.... when you heat cheap mild steel to 1,000*F it starts to rust.

I don't know if it snows down where you are, but a serious problem with header wrap is driving where the DOT salts the roads when it snows. The water is driven out of the wrap by the heat but the dissolved salts remain to cause chloride cracking in metal and absorb water from the air when the humidity is high. I'm wrapped, with no problems, but the car is only driven on clean, dry roads.
