2C -- You have an game going hand and at least 4 cards in a major, so stayman is automatic. 3H would show a better heart suit and a hand that had some interest in slam. Over 2H raise to game, over 2S raise to 3NT. Over 2D, a bid of 3H should show a forcing hand with 5 hearts. (IE, a hand that couldn't bid 3H directly).
