5/10 KK overpair facing turn overbet

[Equal]

I dont have the HH for some reason but 6-handed 5/10 NL.

Effective stacks $1500.

Villain is a tight TAG regular. Decent player, not too scary to play against.

I raise $40 with KK UTG, he is the only caller in the BB.

Flop: Qc7c5 He checks, I bet $80, he raises to $325 I call.

Turn, some club, making the flush. Think it was the Tc.

Pots like $750, he shoves for $1100+.

My thoughts: from my vague read on this guy I dont think he raises a flush DRAW OOP on the flop (but its possible).

Thoughts? Oh, I dont have the Kc.
