They came as part of a 906 engine but I always thought they were from a 69S because of the date stamps. Could these be a later run of 2 litre twin plug racing heads?

    Yes, they are, two-liter twin-plug race heads. Your two heads in the above photograph are 906, not 69S...

    And these 901.104.304.0R stamped 1-68 heads, are they also 906 twin plug race heads?
