1985 300SD Leaking head gasket

Just got done pulling the intake/exhaust manifold and noticed what appears to be a relatively small leak from the head gasket (see photo).

My question is, how serious is this? As far as I know, this is the remnants of an old leak that happened 20 years ago and hasn't leaked since...no idea though. Engine has right at 200K mi. on it.
