elasticity of a a set of titanium valves in a set of C heads

hi was wondering how long would you expect a set of titanium valves to last in a set of C heads?
and what is the biggest push rod you can fit into a C head before running into trouble?
thanks

What is the valve seat material and do the valves have a hard-coated seating area ?

Pushrod will depend on a few things, lifter ,straight or off set, rocker brand and pushrod size , For exp. with WW'S shaft system you will have to do some work in the pushrod holes for the intake . Depending on port work it can get very thin.
