Sadie,
The rear ends are larger diameter than the front.....thats why the NA's made 'em "butt-up".....they used the tail as a hanging decoration by leaving it in place. So like Justin said ....if ya want the "face" at the arrow opening, and facing down, gonna need to cut it off first.
Ya didn't ask but here's some pics of the "usual" way they was made. All of these have the heads "down" but they may help ya out some.
