i own a f22b sohc nonvtec motor . i want to make it vtec . i just wanted to know is that if all i have to do is put a f22b sohc vtec head on my block ?! with that do i also have to modify or change out anything else like distributor cap, timing belt, cams, etc. ?! would i run into any problems with this swap ?! also i was wondering . how much would the vtec head cost about ?! thanks .
