LEAD WITH THE ACES

ANSWER: You have a choice of reasonable actions here. You could raise hearts (which would be an obvious choice if the red suits were switched). Or you could rebid two no-trump, with only your third heart bothering you about this call. To rebid spades would be unsatisfactory because that suit is not strong enough. I slightly prefer the heart raise over the no-trump call. Who is to say hearts will play worse than no-trump?
