1979 10th 400 4 speed cylinder head question

What would be the aproximate date code spread between head date code and production date of a 79 TATA, or would it vary quite a bit given it was the last year of the 400 4spd and scarcity of 400 motors/heads.., any ideas. For example date code of heads beginning of JUne 1978, Feb 79 TATA production date......Any ideas or thoughts. Thanks Chris....

They could be all over the place, I know for the block itself, the last 400 made was around November of 1977.
