vacuum line and high idle

Hello,

Replaced head gaskets on a '91 SC. Car runs, but boost/vacuum gauge reads all the way to the left, idles around 2500 rpm. there is one vacuum line coming from drivers side fire wall which has a plastic elbow(not a T) in the center. I don't know where this line goes. I put all the other vacuum lines where they came from when I took the intake off and do not see any more ports. Can anyone help?

thanks,
Mike
