Depends on what resources you have available to you. I am assuming that you are good on torque so you only want to restrict horsepower with the engine. You could probably do it simply by tuning the engine differently. Obviously would want to work with a good tuner so that you don't do anything detrimental. If you know a good guy he can surely play with things to get the end result that you are looking for without a restrictor I would think. I'm not a tuner so I can't say that for sure. If you can make it happen I think that's the best option.
If not, you could run a "larger" (smaller holes) restrictor or run a more restrictive exhaust. I'm not an engine guy so I can't tell you if one would restrict horsepower more without affecting torque as much. From the little I have read (no real world experience though) I would think a more restrictive exhaust would be better. However, a restrictor plate is much easier and cheaper to dial in to your desired power numbers since you are only changing the size of a hole in a plate instead of an exhaust piece.
As I said, I'm not an engine expert and don't have a ton of experience with this field. These are first and most obvious options I would consider though. I'm sure others on here with more knowledge and experience can give more and better advice than I have. FWIW
