Not quite a quiz, just trie me.

No, I'm pretty sure that they do have 3 heads each. At first I was confused because I have a Tolkien encyclopedia and it said 6 heads (that's why I originally said 6 heads) but I didn't think that was right and I checked in the RotK (the direct source!

They were like great figures seated upon thrones. Each had three joined bodies, and three heads facing outward, and inward, and across the gateway. The heads had vulture-faces, and on their great knees were laid clawlike hands.

Gimli made the family tree for King Elessar, I think.
