I was reading on a 5.9l magnum forum and I keep seeing over and over that some guys are reusing the same head gaskets after tear down and inspection. I was always told, that is something that should be replaced no matter what. Is this a bad practice.

I took the heads off my motor to get some work done and there is no way I am reusing the head gaskets or any other gasket for that matter,

looking for thoughts and a positive answer. Maybe I just like to spend money?
