In general I recommend the following structure:
2♣ (a) invitational with 3 spades, (b) balanced game-force, (c) game-force with 5+ clubs
After 2♣, 2♦ asks...

You can only rebid 2♥ if opener rebids 2♦. Now ask yourself, how often does opener have 4 hearts when it goes 1♠-2♣; 2♦?
As you yourself said earlier, after 2
♣ opener DOES usually bid 2
♦ to ask. This is essential if you have different options in your 2
♣ bid, so it is not solely a GF with long clubs. He will do this whenever he does not have a 55 distributional hand. This means that with any normal hand opener rebids 2
♦, and you explore the best contract. Whether opener has 4 hearts or not does not matter. What does matter is that when he does, you find the heart fit.
