Where you may find a rank at the King's Head (6)

I believe the answer is:

karnak

I'm a little stuck... Click here to teach me more about this clue!

'where you' is the definition.
The definition suggests a singular noun which matches the answer.

'find a rank at the king's head' is the wordplay.
'find' indicates an anagram.
'head' says to take the initial letters.
The first letters of 'at kings' is 'ak'.
'rank' is an anagram of 'karn'.
'karn'+'ak'='KARNAK'

'may' acts as a link.

Can you help me to learn more?

(Other definitions for karnak that I've seen before include "Egyptian temple complex at Thebes" , "Egyptian temples site" , "Temple site near Luxor" .)

I've seen this clue in the Evening Standard.
