Being a '79 carb head I'm guessing it has the passage between the exhaust ports cast into it? You'll see it looking into the thermostat area, a small opening off to one side that goes back into the head. You can also see the openings in each cylinder's exhaust port, but the valves need to be removed so easier to use the first method. Thanks for checking.
Just to clarify, it is a early FI head manufactured in late '79. Being shaved, it is a excellent upgrade for a FI engine and will work well with a properly functioning stock FI system.Confirming this is a 1979 early FI head.
