It depends.

But the addition of a cam alone shouldn't have a very dramatic impact on jetting from whatever you were running before. Also, realize that Dynojet jets use a different scale than Keihin jets. So be sure to specify which style of jet you're using and make sure that when receiving advice you know whether they're talking about Keihin or Dynojet numbers.

It also depends on your location but you shouldn't have to change it for just a cam.
