Best Timing For My Setup?

[smilts]

Hi there. I'm running gt40p heads, gt40 intakes, trick flow stage one cam, 70mm adapter elbow with stock MAF and TB. I also have Ford Racing shortys into a 2 1/2" OR X-pipe. I set it to the stock timing for now. But I'm wondering if anyone knows what timing I should be running with this setup?

14 deg would be the max. 10 is stock.
If you have any idle issues try 12.
