HEI conversion benefits

I have tried to research this topic both here and on the Internet, but I haven't found anything that will answer my question.

Once this conversion is done, can the ECU and the ballast resistor be removed?

I know there's purists here who would say I am blasphemous for contaminating a Mopar with GM parts, but if you can see your way to overlook my transgressions, I would be grateful.

Thanks
