Intake manifold won't seal - How do I check it ?

I still have to check the head angle to positive. I noticed that the intake gaskets on the bottom side that there was a crimp line running right through the area where the sealing ring goes around the gasket port. The gaskets are sitting way low on the head when I put the intake on. The roof of the ports on the intake manifold were partially covered with gasket and the lower part of the gasket is hanging down past the bottom of the manifold. I have ordered some gasgacinch to help keep the gaslkets in place next time the manifold goes on. I am also going to do a little more checking before installation.
