Hot rodding rocker arms

Reducing weight from the valve train is an objective to help prevent the dreaded valve-to-piston kiss of death. People use ti valve retainers and valves and such to reduce the weight.

Has anyone ever gone through the anal-exercise of lightening the rocker arms? If so, any success stories (i.e. engine is still running) and/or verified areas to grind/not touch besides the "obvious" structural areas? Is there a desired weight to achieve? The classic books show how it's done on a Holden or Austin (or whatever). Any real-life 911 experience?

Some company/person awhile back was selling rebuilt rockers that were also lightened, surface smoothed, polished and shot peened. I realize the end result may be equivalent to polishing the valve covers, but I'm hoping for something a little better than that.

Thanks,
Sherwood
