Find me a place in the ITCS that flatly states cam timing must be stock.
I already did George, it's the section that allows you to switch out plastic/phenolic timing gears for metal ones.

<font face=\"Verdana, Arial\" size=\"2\">Cars originally equipped withe plastic/phenolic timing gears may substitute metal gears, provided that the design, dimenstions, and cam timing remain as stock. Adjustable timing gears are prohibited on all cars unless fitted as stock.</font>
Says right there, in black and white, that cam timing will remain as stock.
