Edelbrock F4B manifold owners I have question

[gimpystoy]

W just took mine off after 20yrs. I discovered a 1/2" port on aft pass side plugged w pipe plug.

























i s this a heater hose port . The one in the front same side has the heater hose fitting?
TY,

A picture would help, but more than likely a vacuum port not being used.I would not hook a heater hose to it .

only water port in the f4b is in the front, side by side, 1 for heater, the other for temp
