I think that's pretty easy to answer! Here you can see where we started (013) and where we ended. (075) I think you'll agree, that the end product is vastly superior to what we started with, and will get around a racetrack MUCH more quickly. Although we're pretty happy with the results so far, testing will continue with exhausts, and I still have to finalize the jetting. Plus, work on a new cylinder head spec has already started! Stay tuned.
