this question was brought up on another board i'm on and I thought that f22 are only SOHC. and with my research I've done the only f series engine I can find that is dohc is the f20b. the only accor di think that could have had a dohc would be the SiR..but even that was h22 wasn't it?
so someone please tell me where a f22b dohc comes from
