 The 104^ spacing isn't as critical on the 104 cams since they have the same overlap as the stock JH cam.  You can run them 110/110 no problem.  The 107 cam has less duration, hence less overlap on a 110/110 timed engine.

The hot ticket is the 104/107 combo which you can run on stock 110/110 sprockets.  Heck, the stock cam/107 combo is pretty good as well on 110/110 sprockets. 

If you run a 107/107 combo you'll probably want the 'green dot' to get maximum  top end breathing.  Running them on a 110/110 timed engine will produce more low-end grunt and better around town drivability.
