BB head specs needed - 6272990

I have a set of "990" heads, 1973 dates, that I need info. on. These heads are not listed in any of the books I have and I am trying to determine the specs. and their application. Why are these heads not listed in the Colvin book? Are they common heads and, if not, what are they worth? Thanks.
