Stop in for a cup of coffee

Hey guys, before you all go to work, do I need to replace the cylinder head gasket I removed when I cc:ed my engine?

It says "Fitzco U.S.A 010131". Rather thin, about 0.040". Metal-something-metal.
I used Mopar Steel Shim head gaskets on mine , so I could keep the compression up. Only .020 thick. Good enough for the Factory...Good enough for me...
