Yeah this seems to be a common problem with the LS truck motors at least. I have had 2 of mine do the same thing and one more broke when I was doing a header swap and wound up having to pull the head so that i could get to it to drill it out. But if you have room you should be able to drill a hole through the bolt and get it out with an easy out. If you cant get it that way you can just drill the hole and rethread it maybe youll have room to get to it, but if not you may have to pull the head. As far as the gasket goes they are very tough for stock gaskets but im pretty sure it will fail eventually, but who knows when that will happen.

thats common on the drivers side because it does not have a cut in the manifold between 3 and 5 like the passenger side does between 4 and 6 that allows it to expand and contract. if its not leeking dont mess with it.
