Not Ranked
I don't think there is any horsepower to be gained from using titanium. The weight savings in the important factor. I was having trouble with push rods coming out of the rocker arm at 7500 rpms. Switched to titanium to reduce weight and haven't had a problem since. If you're not having any problems and are using all the rpms you can now, I wouldn't worry about it.
