Cross Over Tube On Back Of Heads
Replacing blown head gasket. What is the intended use for the cross over in the back of the heads. I understand it is to flow coolant, but do I need to run the cross over or can I plug them??

EXTERNAL COOLANT LINES
There is an extra hole that goes into the water jacket on both ends of the heads. These should be plugged when they’re in the front, but left open when they’re on the back. There’ s an external coolant transfer line that connects the holes on the back side to a reservoir that vents the air and steam vapors that would be trapped in the head and cause hot spots.
