Narrative:
During cruise flight at 31;000 ft we experienced a heading failure on the left pfd. We noted the issue and called for the appropriate checklist. Upon running the checklist we corrected the fault by using the revisionary mode as directed. I placed a call to the manager on duty to inform him of this issue. Less than 5 minutes after we encountered the first failure; we now had a failure of the right pfd heading information that was being used as primary navigation. At this time we notified ATC of the issue and advised them we would need initial heading information for our route. ATC provided us this information. We then selected the dual heading failure checklist and ran to completion. I then placed a call to my dispatcher requesting weather information at airports in front of me that we could get into visually. We selected ZZZ as this was clear. At that point we regained our heading information back and elected to continue to destination in visual conditions and completed a visual approach.
