It takes a lot longer than 4 hours to do the swap on a F series. There is more skill involved than being able to change a timing belt. Before you put the head on you have to drill out the oil passage block off in the block. To put the head on you have to take the cams out of the head. You also have to know the proper technique for torquing the head. Then you have to put the cams back in. Theres a lot of stuff you have to do. Its not like you can unbolt the stock head and bolt the H22A head right up.

Calling this combination a "G" series or a "G22" is a stupid name since honda actually has a G series, and calling the Fseries block/H series head combination a G series makes it even more confusing. These engines usually have issues, which is the reason why every person with an F series engine hasn't performed the conversion.
