The correct usage of z-parameter transformation is:
Z_param = stoz() if your s-parameter ports have 50 ohms
Z_param = stoz(25) if your s-parameter ports have 25 ohms
This works in equation components only, not in diagram equation.
Anyway, if you want to know the loading of the source, stoz() is not the correct function, because z-parameters are defined with open port terminations.
rtoz(…) does the job (see attached picture).
