If you don't own the proper tools, installing a headset or bottom bracket can be troublesome. When you buy a VO frame, headset, and bottom bracket, you can select the appropriate labor charge for installation. 

Note: for headsets, we only press the cups into the frame (the part where you need special tools). To ensure everything arrives safely to your doorstep, we do not install the fork. For sealed bearing headsets the crown race is split, so do you do not need any tools for installation.
