Do you have any data from track days before and after this mod? Or did you do your race engine all at once. Is there any noticable performance advantage or is it only seen through improved reliability and decreased wear upon overhaul? It would be cool to see a car with this modificationo using a cylinder head temperature sensor and logging the data throughout a session on the track.

This seems like a simple machining operation- easier than twin-plugging. While not necessary as on a racing engine, I would think a street engine could benefit and I see no downsides to doing it "while you are in there."

Cool stuff, thanks for posting. Sorry I stole your photo.
