Rear cylinder head water connection.

[Gronberg John <john.gronberg@us.landisstaefa.com>]

I am at a point where I am reinstalling my repaired cylinder head.  My
question is, the water connection to the rear of the cylinder head that runs
up to the front of the water pump connection.  Is this connection left open
so water can flow or is the line "plugged" so water can only flow from the
front of the engine to the back and not "split in the middle"?
