Hi all,

I am doing a head gasket on a 1995 e320 Wagon and I have a seal that came with the head gasket that I do not know where it belongs. The head gasket kit is Victor Heinz and the seal is just over an inch and a half in outside diameter. It has an arrow pointing clockwise and the letters:
"SHR2" "30" "40" "7" "4".

Where does this go?

Also, any famous last words to someone about to put the valve cover back on?

Thanks very much,
Jim Lee
