after taking some notes with the new cam timing of the 09ZX6R, they run higher numbers....I had my intake set at 99, and the stock intake was at 106 or so(due to the milled head dropping the angle some). The idea for the motor was a street grunted performer, and with the great midrange i figured it was worth s swap and see if there was any loss in fun factor. No losses to be concerned of, if any, works and pulls smoother in my book.

I'll go to the drag races next year and if it's better i'll leave it in, if not, drop the old one back in and see what's what.
