Makes sense. thanks!

This is kind of an odd question... it seems that almost all Alpha/N setups are done with ITBs. Is there any reason for this other than the ability to tune individual cylinders? Is there any reason why I shouldn't use Alpha/N on my standard single-throttle body engine to use a long duration cam on ...

No, peak power will occur in the region of 12.5:1 - 13.0:1. Your exhaust gas temperature will be dangerously high running stoichiometric mixtures at WOT, you may even lose an exhaust valve or two.

How hot is dangerously hot? I've never seen numbers for this.

You want to keep the EGT ...

I have read this thread through a couple times and find it very valuable. It is helping me solidify some of my tuning beliefs, but I had a question about the above statement.
Fantastic questions! I will answer them as well as I can.

Doesn't knock/ping happen when your combustion temps/pressures ...

I always thought that if you want maximum power, you have to find the AFR that gaves you the max power, and most of the time, it's around 12,5.

No necessarily. You might get max power, and insanely high EGTs that melt stuff at around 12.5:1, for example- so you would need to go richer ...
