the vtec system is basically the same, only the switch contols two cams in parrallel vs one. the head from the h-22 will bolt up with some modification, though your best bet for ease of installation is just swap in a h22.
note: engine swaps kill resale value, you not only pay upfront, but in the rear of the transaction. a headswap will result in the same.
in a finacial sense, if you have the funds sell the car and buy a prelude.
in the fun side, stick with the accord.
