Vai is indeed about 5'11.5". I met him at a masterclass, I'm 6'0.5" and he looked about an inch shorter than me. He's similar in height to Richie Kotzen, which I've also met (he's closer to 5'11" flat). They're both very nice guys, and great teachers!

Rob, have you hear Zappa's music? if so, what do you think about it?

In any case, Zappa is clearly taller than Vai by half an inch.

(Revised) I have been a long time Frank Zappa fan (since 1964). I have seen Frank Zappa live in concert 7 times and I doubt he is much taller than 5' 9". Clearly he is a Giant to me, but I doubt he is 6' tall.

Zappa frequently wore boots with heels. He was also very slim which boosted the illusion of him being taller than he really was.
