If you go for Ti I've read that valve spring pressure will determine how fast galling will occur. Food for thought

I'm running factory (00-01) intake springs on intake and exhaust. Titanium retainers (Skunk 2) and aftermarket light weight valves. The decrease in valve train weight (10%) from the ti retainers and valves allow me to see 9650rpm with no difficulty on the factory springs.

Have you done any inspection on your head? How much mileage do you have on your head? Which valves did you go with?
