CIH 16N Nock

Moinsen! I need a cam for my new motor CIH 16N. The 16N has not been installed so often, so the cam is not so numerous in the wild. Now my question: Does the angles fit the ones of the 17N/S? Or even those of the 19N/S? How are the angles? Thank you! (p.s. please don’t take any hints, take another engine oä, because that’s not an option for me.)
