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.
