We have an engine code article in the reference section near the top of the forum list if you want to look through it.
The F22 and H22 are engines that are either stock with the Accord or easy to drop into one. If you pop the hood and look at the front of the block near where the engine and transmission mate together, there will be a small flat spot with some characters stamped into it- the top line is your engine code, and the second line is your engine's serial number.
