Dan,

I had very liberally coated mine the first time as well, but that one pipe still managed to leak. You might try the wiggle test that I described. That won't be conclusive, as it could still be leaking in a small area rather than the entire joint coming loose. You could also closely inspect the joint to see if you can see any soot indicating a leak. As for my header gaskets, I purchased my headers ceramic coated from ERA and bought their gaskets also. I just got my ERA invoice out and it lists "Primary pipes, set of 8, with special gaskets". So, I don't know specifically what they are.
