Default What Valve Springs to Use?

Hey Guys, I Recently broke a valvespring. My problem is that i am having problems getting the exact spec on the camshaft. I am told that the cam has .598 lift. It is quite aggressive. This is on a .30 over Iron block 408 with stage III Ported heads and fully built lower end. Car is making around 530RWHP and 510 RWTQ. I need to fix this ASAP so any suggestions as to what valve springs would be safe to install in this beast would be greatly appreciated. Also while doing this job i am replacing the valve seals, any assistance as to where i can pick those up from would also come in handy. thanks guys!

I also have the PRC's for the past two years. They work great.
