Air Injection Plugs

Hey everyone. I recently purchased a set of threaded plugs for the air injection holes on my exhaust manifolds. I am wondering what is going to stop exhaust gases from leaking around the threads. There is no head or shoulder on the plugs for a washer to seal like on the air injection manifold.

Any high temp thread seal that I can think of is only good to about 400f which is not even close.

Please anyone have a suggestion....
