they are electronicaly sensed to advance/retard ECU effects on fuel/spark maps.
Out of interest, why did you put the ST bits into Silvertops ?
Why not just use the black top head ?
With the VVT I understand that its not simply on or off, however I know a few guys who either have their VVT on a manual switch or it is switched to the ON position using the shift light function on ECU's not capabale of controlling VVT
What effect does the bolt in the oil way have ?
