Drill the teeth valleys first leaving material, mill around profile with larger endmill, then just final finish with the small endmill.
I emailed gates a while back to ask if their online 3d model generator of pulleys gave an accurate profile of the tooth and they replied no, but you can request up to 2 files per month from them of accurate files of gt2 pulleys. Definitely something ill consider. Delrin would make a nice light quiet pulley.
