Ditto on that one.....

Did you mean to say, what style is preferred, the Race or emissions? If that's what you mean, it's personal preference. If you are tuning the EGR and AIR out, then I'd do race style (no fittings or provisions for EGR/AIR), if you dont want to tune out, do the emissions style. To me, it's personal preference (I did emissions).

Your WOT AFR will not go rich, it will go leaner.
Your closed loop AFR may vary a little from stoich though due to the O2 sensors being farther down the exhaust steam, which cools the sensor down.
A tune is definitely not needed after headers.
