Not sure why you're over-looking this question.
As for whether the Quranic verses are metaphorical or not - I view them as metaphorical, others may have a different view. Both verses are 'historical' verses of the Quran, and as God says in the Quran:
“He it is Who has sent down to thee the Book, of it there are decisive verses: they are the basis of the Book and others (which are) ambiguous. But those in whose hearts is perversity pursue, forsooth, that which is ambiguous, seeking to cause mischief and seeking to explain it (as they like).”(3:7)
Let me ask again - are you one of those who believes Noah lived to 950 because the Bible says so?
Cheers,
