My knee-jerk reaction is that you should use the later intake gasket;
The only difference is the crossover area;
I have seen some aftermarket generic intake gaskets (maybe they were old stock) that had a small circular hole for the crossover - which appeared to allow mixing and matching of intake vs heads...
I think I had this scenario when I owned my brother's '73 Formula - I had a '77 (W72) 400 shortblock, with '69-62 heads, and a '72 intake manifold.
I will look into this - because I want to know...
