I wouldn't call it a lot. It might be "a lot" to someone who only works on bikes, but it's not really a lot as an overall fastener torque. On my lockrings I use a 12" crescent wrench. 30lbs isn't very much force for me to put on, I don't have a torque wrench with me, but I can guarantee from feel that I'm putting much closer to 60 ft lbs on there, never had a problem overtightening them.
As everyone else has said, that's a Shimano cassette and an aluminum freehub body. Campy cassettes don't do it, and SRAM cassettes don't do it much, because of the way they're designed.
If you want to run Shimano cassettes on an aluminum freehub body, get the American Classic clips mentioned above. You'll have to call American Classic (unless it has changed), they aren't listed for sale anywhere.
And by the way, 30*12 isn't 350. Just thought you should know.
