Longorange, I've been meaning to answer more of your questions but don't have much time lately. I can tell you that My Clifford shorty headers look 100% better than the Stovebolt cast iron headers I used to have and they perform just as well. Although the cast iron headers will last well into the next lifetime, my Cliffords are ceramic coated and will last a loooooooooong time. I've also never had a problem with sealing either of them properly. Currently I am running 2 gaskets on the head but only for clearance issues. If they're tightened properly you shouldn't ever have exhaust leaks at the head.
