how does milling the cylinder head affect the valve timing??

The teeth on the timing belt most likely would not perfectly align due to the shorter gap between cams and crank, so to get timing set perfectly you should use adjustable cam gears. I'm assuming at most they will be a degree or two off, so it may not be very noticeable if you ran without the adjustable cam gears.
