High Ratio Rocker Arms

Reading about performance mods for a 1999 slk230, and it seems like it is basically limited to a larger crank pulley swap to spin the SC faster, and ECU tuning.

Apparently the cam option is a great deal of work for little gain.

Has anyone installed higher ratio rocker arms for longer valve open time?

I have not, but I am interested in the cam option, what companies out there make cams for our cars?
