Thank you for the donation,
As I am a little unfamiliar with these engines, I will talk about the theory side, which should clarify any points you may have.
The difference between the two engines is basically what is called the swept volume, that is the total displacement of the piston, there is a good chance that the 2.4 head is identical to the 2 liter, there may be a very small difference in valve size and cam profile but this alone would not make any noticeable difference in the drivability. There is an old says "there is no substitute for cubic inches" that is the more swept volume the better the engine, taking into account other head work that can be preformed, basically the difference you will feel is a better responding engine due to the lower end over haul, the head will be of minimal consequence I feel. The only thing that you will have to make sure is that the new head is compatible with all manifolds etc from your original engine.
