Is it bad for an exhaust manifold stud to come out of the head? I was taking off my header and when I put on the stock manifold, i gently started tightening a nut and it felt like it was spinning in place. Next thing I find is a bolt that's covered in aluminum on the threads.

What does this mean? I've got a ATK Remanufactured engine. Is this a weak head? Could the place that installed my motor have tightened the manifold on way too tight?? I made sure that the nuts were on snug when I had the header installed but not tight-extra tight.
