Question What valve springs to use?

Hi,
I'm rebuilding the engine and am debating on what valve springs to use.
My plan is to go with titanium retainers but am deciding on stock vs stiffer springs.
My understanding is that stiffer spring will both rob HP and put more load on the cam (hence wear).

So, does anyone know what safe RPM can the stock valve springs sustain?
The car is mainly used on track and I can see me revving regularly to 6700.

Thanks...
