I've had the same problems with my VOR Receiver. First of all, I've used a sampling rate which allowed me to have 1 degree per 1 sample. (Each sample the signal increases its phase by 1 degree).
I've used a delay block on the left hand part of the flowgraph along with a "calibrated signal", adjusting the delay I was able to null the output of the comparator. This way the receiver was calibrated. The signal was generated by another flowgraph that simulates a VOR signal on radial ZERO. VOR signal normally has 1 or 2 degrees tolerance. Hope that helps.
