Default Dynomax Blackjack header gasket

I'm installing this header in my 88, (see build thread) and was wondering about this gasket that came with it.
It appears to be paper/fiber of some kind, and doesn't have the "squish" rings that I've seen in the past. Is this some new kind, or just a flimsy pos, I want to know if I can run it with no worries.
Thanks.

Even if I used copper RTV? I'm not trying to weasel out of buying a new one, just wanted some info on why this one's so crappy. I'm guessing it will burn through around the exhaust ports?

paper header gaskets dont have a very long track record if it were easy to replace it would be fine for me and the amount of work involved i would rather have a metal/silver or something with a more heat resistance just my 2c worth
