It's worth mentioning that the film transport has to be set up for 220 for the thickness to be right. 220 film has only a paper leader and trailer, no backing paper behind the film itself like 120 does, and thus has different dimensions. That's to make the film - which is twice as long - fit on a standard spool, and to make sure the frame counter works correctly.
You either need a 220-specific back (Hasselblad, Mamiya 645, Graflex) OR you have to change the pressure plate and - possibly - a camera setting (Yashica TLR, Mamiya TLR, Fuji GA/GW series cameras). This ensures that the film is held properly in place for the 220 packaging and dimensions.
The other issue is processing. It's doubtful the OP will find anyone still processing 220 (not impossible, but unlikely). That means you need a 220 reel and, perhaps, a tank (both of which are much larger than a 120 system). I use a 220 Nikor reel, but I process it in an open tank in the dark - three tanks, actually, to be precise .
