Getting the template will save you a lot of time and effort. You will be getting holes that are proven and work. Most of the other flow characteristics are from what is done before the port and there are not any templates for those. This is where the flow bench really comes into play. Many of us have our own templates and will actually vary the ports to specific applications.
If you have never ported a rotary before and you are building a street car, a template is the most cost effective way to go and will yield you good results.
