That gasket is known as Bob where I live.
A BIG help would be to note the vintage. I am guessing you have the dohc 2.3, but don't know the year.
I could not find it individually, or under 'intake' or 'head set', but it showed in the 'engine gasket kit' sets.
It appears that it connects to the crankcase, given the color of the walls. Is there an oil separator mounted that keeps the oil in the pan, but passes the crankcase vapors to the PCV valve?

Added: It will come in the FelPro head set.
