Mines may 09, so don't know if it's just limited to early ones, maybe all fg owners should be having a look. Unless they mean all series 1 fg are the early ones. The gaskets are rubber so should be right to take off, have a look and put back on, but being rubber they do go hard, so probably depends on how many ks on them to what sort of condition there in. Genuine gaskets aren't expensive, cam cover, 6 spark plug tube seals, 2 vct gaskets $113 from ford.
