| Base circle is a base circle. Take a micrometer and measure it for your cam and for a stock cam. The JWT uses the same base circle as stock for every cam except for the 500 cam. I don't own a pair of Jun cams so I cam not completely sure of its base circle. You keep going back to the fact that you have to mill the head to clear like that is a form of measurement. The only form of measurement is a micrometer. And you also have side tracked the issue of the ECU and the VTC.
