With the thin header flanges (1/8" to 3/16") that most Cobra mfrs use you're much better off to use a copper header gasket like SCE (that's what I use). The flanges tend to distort and move around somewhat. Any paper/composition gasket, hand made or not, is going to fail eventually. Do yourself a favor and go copper. Also, use a set of Stage 8 locking header bolts. They will help control flange leaks too. As stated, it's all available through Summit or Jegs.
