Oily spark plugs

During the changing of my spark plugs I found that cylinders 2 and 3 have some oil on the bottom of the plugs. Cylinder 3 is completely covered and cylinder 2 is just a little wet. Cylinders 1 and 4 are dry.
I have a CEL code for misfire on cylinder 3, but aside from the CEL there are no symptoms of a misfire.

I am guessing this is a bad head gasket, but not sure, as I don't know that much about engines. Would this be a correct assumption?
