I would believe so , as period evidence is available to confirm anything/everything was done in 1972 which is why the FIA relented and allowed the alloy block for 1973 , but you may find Peterson/Mass ran an alloy block late in season , John Gale's 722-5 did which is why it is allowed that over here , and that is speaking as an Eligibility Officer and also an FIA HTP representative for Australia.
The other interesting point is in regard to engine capacities , I have a few 1972 programmes for the F2 rounds and virtually everybody listed their capacity as 1997/2000 cc, none of which were correct , the biggest you will probably find is 1970cc and not many of them , lots of 1930 / 1860/1840 etc.
