I changed to the Taylor 8mm wires with the spiral whatever center:rolleyes: No change in RPM's

I also run with Jim V's modified heads I get a little puff of blue smoke at start up only. He has a logical explanation for it I just can't remember exactly what he told me, something about running a valve cooler and leaving out one of the two seals (not sure):rolleyes:

I am very happy with the cam change and head work, it gave me a nice strong reliable setup.
