The intakes are Ti (which are very soft), once the coating wears off they start sinking into the head and hence require constant adjustment. If you've already shimmed 3 times in 6 months I would be worried to ride it as you may cause some serious damage.
You'll need head work. At minimum, new intake valves and new seats. Wouldn't hurt to replace guides and springs at the same time as they are pretty cheap.

As far as SS valves, I believe the initial cost is slightly higher (they also require heavier valve springs) but they are much more durable!
