header gasket keeps blowing out
header gasket keeps blowing out i have qtp headers and ive been using the gm metal gaskets. i keep getting a leak on the back primary on the drivers side header. i already broke on bolt back there trying to tighten it up too much, is there any trick to stoping the leak....when installing new gaskets, ive been tightining from the inside bolts out, from what i understand that is the correct way to do it.
that was already a problem, one of the bolts was bottoming out and i broke the bolt off. my mechanic put in new bolts, obviously he got the one i broke out. and new gaskets. being it is metal, the gm gaskets, if the bolts loosen up at all, when you retighten them, will it seal again or is the gasket blown out?

I don't think you can blow out metal gaskets. Most likely they are not your problem. I agree with checking to make sure the header is not bent or warped. If you don't have washers on you might want to try that too, to make sure the bolts aren't bottoming out. I've heard of people adding an extra gasket as well.
