Speculation is the head came two ways from Williams:
One with decals trimmed about a half inch back from all 4 sides of the head--and another version with artwork all the way to all 4 sides of the head:

i have both sets of films in my possession right now and was discussing
this very thing last week when i was at ipb. here is a pic of the
artists original drawing in negative form. if you look closely you can
see he wrote some notes. but its nothing to explain the 2 versions
though

when reprints were made williams/bally often used different printing
companies than the original printer usually for timing purposes, not
quality. this is factual based on the records and notes i have read.
wms kept incredible records, youd have to see it to believe it. in some
cases the artist made comments to them about the final product and when
the reprint was done changes were made. in other cases the films were
misplaced/mishandled/lost and they had to output new film and without
specifications some judgement calls were made.
perhaps with roadshow (and this is sheer specualtion), the reprint was
done by another company and no films were available for them on the
backbox. maybe they havent printed backboxes before and made a
judgement call to print within the backbox. i could not find any other
documentation. maybe someone else knows the real answer.
i found 5 revisions for cftbl playfields. i honestly didnt spend any
time looking for the reasons why and which revisions were used."
