You say you plan on getting a Racing Beat header but you haven't said which one. The street header is a bit short for stock ports, and will be worse if you port the exhaust. I would suggest the road race header collected shortly after the flange(will vary depending on your ports and peak RPM) or the AWR header which is built for streetported road race cars.

If the motor is in good condition you should not have a problem breaking 160whp. My 180k mile S4 motor was right around 160whp with stock ecu.
