I dont think you'll see an improvement from the valves alone. Perhaps there is some power left on the table due to the valve job that could be addressed.

With your relatively low RPM ceiling, the weight savings of Ti wont gain you much unless you are willing to chance running lighter spring pressures and even then its debateable.

The Ti valves would need beryllium copper seats.

Ti valve tulips are often thicker as well, so you may see a small decrease in chamber volume.

The .030 deflection is what Brett has always told me to expect.
