FH on Flop - But Villian has draw to possible Higher FH

[JanelleBB7]

So I know villian very well. In fact he is a friend of mine. So there is NO DOUBT in my mind villian has the K here. My question is this... Should I push this flop with my boat here before the turn or should I push it on the turn if he takes no interest? I know he will either think I have a Kxxx like him or that I am fully boated. He knows me and knows I am a good player and would not be pushing with anything less than Kxxx.
