For the good of the ZR1 share.

If you want the thermo to work you have to make sure the bypass works, its how the warm water acts on it so that it opens. You cannot just block the bypass. In addition if you do anything that changes the water flow at higher RPM then you need to replace the radiator first as the stock radiator cannot handle the higher flow, thats why the bypass was developed.

If you are going to use the car in a racing application or for summertime use you can cut the thermo spring,

AND replace the radiator with a higher flow unit. This modification will result in the coolest water temps. I ran this in Florida for many years and saw water temps on the interstate of 170 deg in 90+ weather. In town ran 190 200 deg.
