Hey, Raven,
Quote: "Actually the book doesn't state where Zephods second head it, in-fact the only real reference to it is Auther's comment 'Of course, he only had the one head and was called Phil...'"
Not quite...
Quote: "[marvin takes Arthur and Ford to the bridge of the Heart of Gold] Arthur followed him in nervously and was astonished to see a man lolling back in a chair with his feet on a control console picking the teeth in his right-hand head with his left hand. The right-hand head seemed to be thoroughly preoccupied with this task, but the left-hand one was grinning a broad, relaxed, nonchalant grin."
I think it's pretty obvious from that.
This is actually about 4 or so paragraphs before the quote that you gave... So I don't know how you missed it.
I got that from page 94 of THHGTTG The Trilogy Of Four ( Picador ).
Jess.
