Swapping the whole trans would be easier. You have to pull the trans out and open it up to swap gears, and you only have to remove the trans from the car if you're swapping.
The HF has a taller top gear, and it also has a different ring and pinion ratio ("final drive") so that every gear is even taller than it would be in a DX or an Si transmission.
The DX (standard) and Si actually have the same gear ratios, but the final drive ratios are different which effectively gives the Si shorter gears all around. The individual gears for the HF are all taller (except possibly for reverse?) and the final drive is taller as well.
