So Warren, are you saying that both of these heads were cast in 1968???
And that these are cast in 1969???
These are a given...they're 1973
IMO, the first head was not in 1968. The numbers are cast just like the '73 head. Which to me says it was cast at least sometime in the '70s.
The second is 1968.
The third...I have no clue. Although I have seen cast iron 291's with similar castings for dates that were over the counter heads.
