or/and too much high end power that it could possibly kill the gear box at high rev?
and would the power gain from changing cams more significant then changing the header?

The S4 cams are definitely more aggressive than the S3. As I understand it, they have a pretty lopey idle. I don't know much more about the S4s. It seems that nobody really goes for them.
I'm not sure how they would relate to an AT. A pure guess would be that they give up low end torque for high end power. I'd stay with S3s.
The S3 cams are similar to the Hotshot header in terms of gains.
