I can appreciate that the titanium is a lighter valve, therefore you can spin the motor a little faster and it will save on valve springs.. So I guess the question I have... is spending the extra coin now really worth it, once my butt gets strapped into the seat?

Also, I was reading elsewhere that an inconel (or some super alloy) valve is recommended for the exhaust... since I'm more in favor of a bulletproof motorover squeezing out every last pony.. wouldnt I want to get a stronger/harder valve and not worry so much about breakage?
