Depeding on the cam duration you will need to increase the idle advance somewhat.
For a kent FR32 or Piper 270 you would want around 12deg advance at idle
For an FR33 or Piper 285 you would want 14-16deg.
Bear in mind you will also need to limit the max adavance to 36-38 deg which may require dizzy modifications or an aftermarket one. This is because by
increasing the idle advance you are also going to increase the all in advance to beyond a safe level and you may experience knocking under load.

There are some modifications you can do the existing dizzy here....
NW Hoodies
Or shell out for an Aldon one...
Or investigate a Megajolt or similar
