Default ls6 valves and PRC EHT .675 springs

So I recently picked up a set of ls6 heads with the hollow/sodium valves that already have some brand new prc .675 springs on them. I plan on sending hese to AI for porting and will be running one of their custom cams.
I have been told by a few people that they have "seen" dual springs with high pressure break the sodium valve stems off.

Is there any truth to this or will I be fine running the springs I already have?

Without knowing the new cam's lift it is not possible to say.

I would imagine AI can advise you on that.
