He raised PF from early position and the Ah and Qh are on the board. Unless he opens sc's utg it's very unlikely he's flopped a flush draw. Also, the fact that if he had opened a hand like 78hh he would most likely continuation bet the flop with that hand discounts him having a heart draw.

He could have a hand like KQcc/QJcc/AXcc that he decided to c/c on the flop. To me those make more sense than AA/QQ that I feel can be discounted because of the drawiness of the flop.

A final note, I fold PF about 100% of the time here as AQo is quite dominated by a standard tagg's utg opening range which a lot of times may not even contain AJs.

Looking back on the HH AJ makes the most sense to me. I do not fault you at all for calling. Make sure you take a note on the hand you're shown and how he played it. He made it 5x utg (was their a poster) which isn't exactly standard, next times he opens in EP check the size, if it's smaller note the hand he shows down in that spot.
