SM Head Install... forgetting anything?

@mopowers its just the metal looking gasket that came in the felpro gasket kit. I have my old gaskets as well. @DARTGAME they only go on one way? As they hook over the last stud in the headers. Maybe they could be on backwards, with the other side supposed to be facing the headers and one facing the machined face of the heads.
In this picture, the header gaskets are shown right side up. Yours are on upside down.
