Where should I be with my timing??

So I've recently made the switch over to fuel injection and everything was great. I then made the switch to use the full gamut of the sniper system to add Timing control. I'm now a little curious as to where I might get the best results with my timing since I can control it so easily.
The sniper's default settings are: 15 initial, 36 total cruise, 32 total WOT.

My engine specs:
440, lunati 60303 (.494/.513 lift, 110 lsa, 268/276 dur.) 9.8/1 compression. sidewinder ported heads,

Now, while yes I'm looking for numbers here, I'm more wanting to know the how and why OR how to find this out for myself what timing works best in my application. I can do alot of things with my car and figure things out, but for some reason, timing seems to completely fog my mind.

As always thanks for the help guys.
