Hello I agree I would get the longer one and cut it, but if it was mine or a good customers frame I might stack/space the headset about 8-10 cm. I do this 1 beacause at some point a taller headset might get used. 2 since you are using a quill stem it gives you an extra 8-10 cm of height. but this is just my humble opinion
