renesis rotors dont work well in a peripheral exhaust ported motor (non renesis) The apex seals in the renesis arent nearly as tall and tend to break as they pass over the exhaust port.

The performance numbers between 9.7 and 10.0 rotors arent going to be that different anyway to warrent running the setup

 

I have been told that milling and running stock rew 2 piece is the way to go.

And I know of a guy around here that says he loves the “no boost” low end power he has for the street with the use of the renisis rotors.
