For the price and the time your gonna waste you might as well do 918 springs just to get it out of the way not that big of a deal IMO Good luck
That way if you wanted to go with a bigger cam dont have to worry about changen the springs agian to match the cam.

I'd go with 918s with that cam...although the LS6 springs might handle the lift, they might not handle the ramp rate. Since that is a Crane/Vinci cam, I'd ask them. Valve springs are not something I'd cheap out on being that they are so critical to the engine's operation.
I would go 918's as well, I have the same cam 
I am currently running that cam with PSI beehive springs, it will run forever in RPM without a hiccup so the 918's would be a great match.
