Does zscor normalization requires a normal dataset? Also for skewed data are we going to see similar amplitudes for the normalized data?

I had normalised two non normal dataset which are correlated to each other ( r=.65). When they are normalised and ploted, their amplitudes do not match accurately. I was wondering what is the...
