20B N/A with RX8 rotors??

My only concern with Renesis rotors is that they aren't designed to handle peripheral exhaust ports, so I have no idea how long the lighter/shorter apex seals will survive.

Aren't you supposed to machine the rotors to use standard 13B/20B apex seals?
EDIT: Just searched evil forum and I guess it's not necessary, but I did see that the standard renesis seals warped too much on the peripheral exhaust ports so ceramics had to be used. I think if I were doing it, I'd use 13B seals. Also, the thread I saw was from 2004, so things may have changed.

I'm interested in seeing more input on this.
