Coatings available for ported heads

[SappySE107]

there aren't any tests so how am I supposed to know what is the best for headers?

yah thats kinda what i thought, i had heard about an afterburner coating that was supposed to be awesome, but i dont know who makes it. it was in some type of thermal imaging website, they tested 3 coatings and the afterburner won the test, by keeping ambient temps down outside the header, keeping the exhaust gas hot and not allowing much heat exchange from gas to header tubing at all.

the headers are on my car right now, and i dont wanna have to take them off and put my stock manifolds back on, buy the stupid studs that twisted off(5 of em) and then wait for that, i would just rather get another set, have the bung welded in, and an offroad pipe for my cutout.
