Darn, I hate when this happens. To other readers: please scribe the three bolts before removing the cam gear.

All you can do is to center the bolts and hope. Before doing this, releve the tension on the VVT by lining up the timing marks, rotate the engine 90 degrees clockwise and then coming back to the timing marks.

As to your other question, the installed intake cam slot is above the center line and the exhaust below the center line.
