so i got the GT-40 heads yesterday. they really dont have the thermactor ports in them. they do have GT stamped on them as well as a "71" up by the valve cover openings. what year heads are these???
they do have 1.84/1.54 valves, and the 3 bars on the end of the heads.
could somebody help me identify the year of these heads? or are they some sort of aftermarket motorsport head???
thanks in advance,
adam
