Whats more important RPM's or EGT's?

In terms of engine life what is more imortant? I can spin my stroke @ 3000 and it isn't getting hot but is this bad for it? I know the more revolutions something makes the closer it is to the end of its life but... I guess I want to know if I run it down the interstate @ 3000 will the

3000 rpm @ 900-1100 deg F all day long wont hurt your engine life to speak of, keep your oil fresh so you dont have foaming issues and keep the air intake frash also, youll be fine. But drop those RPM's to 2000 and increase that PYRO to 1350-1400 and you had better not do it for more than very short durations or youll find your exhaust valves stuck up against the turbine.
