If it were me, I would listen carefully to the kick mic both in phase and out of phase. Your kick mic will always be "out of phase" when dealing with overheads. Whether or not it sounds better in and out of phase is dependent on many other things not barring personal preference. I recomend always listening carefully before just reversing the polarity of a mic. Sometimes it sounds better when double micing a snare to reverse the polarity o the top mic instead of the bottom. Sometimes it sounds good to not reverse either mic. The point is, I would not blindly do it, but listen and think about why you are doing it and also about why you might not want to.
