With regard to rotation, if you're using the dual-fire Dyna S that has ONE POLE in the rotor, rotation doesn't matter.
I made up a timing events diagram to prove it (I need to diagram things out for myself sometimes). This diagram will be helpful when making/modifying ignition system on all 45deg V-Twin motor 720deg firing cycle.

If you really want to hide that Dyna, you can convert a stock HD timing cup in about an hour. I've done a few of these for friends.
