Calling this seriously depends on what range you are putting utg on. You have decent equity against a fairly wide range:
Board: 6d Kh Qh

Wins Ties Equity
39.17% 7.86% 47.03% ( AsKs )
45.10% 7.86% 52.97% ( AK, KK, QQ, ThJh, KQ, 66, AA, KJ, KT )

but taking out the junky K hands, your equity falls dramatically

Board: 6d Kh Qh

Wins Ties Equity
7.75% 12.91% 20.67% ( AsKs )
66.42% 12.91% 79.33% ( AK, KK, QQ, ThJh, KQ, 66, AA )

generally, I think that on this texture board in a reraised pot the second range is more realistic. To put it simply, there are way too many hands that beat you on this board for me to make this call. In fact, I probably just call the flop and fold to a strong turn bet
