in that case, i dont understand why you want want to do that, you would lose power doing so as the f22 stroke is 95mm and the f20b is 88mm

i would say just sleeve it and do forged internals and you will be fine, no need to destroke, but if you really want to i would say use a h22a crank

the f22 has pretty low compression stock, and if you do forged pistons you could get whatever compression you wanted

and yeah the h22a would drop right in and take almost 5mm off the stroke
