Initial Timing for 416 Stroker startup

Hey,
What did you set your initial timing at to start and break in the cam on your 408/416 stroker motor. I have edelbrock performer aluminum heads and a Lunati 276/284 valve lift 513/533 Holley 750. Starting for break in I understand needs to be real close to prevent any issues. I think for a stock small block it is 12 degrees before TDC. I am trying to figure what I should set mine at?
