At what point does a conventional headed BBC combination need to seriously consider putting titanium valves in?

Is it based on RPM, or a combination of RPM, cam intensity, etc?

If RPM, what seems to be the point at which they are recommended?

It is all about lightening the valve train due to RPM and the cam profile, I would say around 8,000 on the RPM and around an .850 lift would be my starting to consider it point

a few engine builders i asked also mentioned valve size/weight and bigger than 2.30 a pretty good idea to go with tit.

I have SS 2.350 intake valves. They seem fine and I have taken the motor to almost 8,000 on several occassions. I hope to do titanium intakes when I freshen it up because the intake springs are going away while the exhaust springs are still the same as installed after 150 passes now. I think the heavy intake is killing the springs. JMO, RM
