stay with ti valves. the yfz is designed with these valves for a reason, they are way lighter and help the engine rev faster. stainless valves are good if your driving a sunday street cruiser and still want to have some fun, but if your looking for seroius performance then TI all the way.
2006 yfz 450, 480 athena bigbore, cp 13.5:1, wr crank, stage 1 hot cams, +1 intake valves, porting by Flyins Prostreet Engines, fci intake, dynatek cdi, jsr exhaust, pro armour nerf bars, fox floats, asv levers, moose throttle, odi lock grips, g force axle, itp t9 wheels.
