I've got 3 very good looking heads from a 1968 911L. Air injectors still intact and in place. Fins good, everything looks good. At the least I would lap the valves to make sure they are good. There is a slight amount of surface corrosion on some of the bare steel (studs, springs). See the pics. 39mm intakes, 35mm exhausts. Smaller valves but same 32mm ports as the T & E, I believe.
All three for $200
