well i called MSA today and once again got their world class customer service (they even called later to see if things were ok). its great that they are technicians and know what they are talking about, they told me to go ahead and try the header and if it popped out my studs the would replace the header and the studs...
i tried it, it worked!!! well so far
my advise to anyone in this type of situation is to call MSA first
also i wish motorsport auto would make some "I ♥ MSA" stickers cause i sure do
