If you run stainless you'll need to go with stiffer springs because of the weight difference. They last longer (spec wise) than the Titanium valves but are more prone to break rather than bend. I haven't heard anything about the stainless breaking though. Either way, I don't think you can go wrong with either. What do you intend on doing to the motor?

Stay with the stock valves unless your going big bore.
