I've got Racing Beat's porting templates if you'd like to see them. They include instructions on where to place them. You're about 15 miles away from me, according to Mapquest. Feel free to call me at 630-682-9225 if you want to look at them or borrow them.

I read on Craig's rotary site references to 'street porting' the engine to improve breathing and power output, but I haven't seen any mentions of port modifications during the 5 months I've been reading this group's postings.

Is there info in the archives, or another site that would provide diagrams or photos of what is done to the ports to improve breathing?

I am rebuilding my 20B as a normally aspirated engine to install in the RV-10 I am building, and the 240 HP from stock is a little less than I would like. Any input would be greatly appreciated.
