Valve Springs with this cam....?

What vavle springs and retainers would be recommended with this cam?:

Int. exh.
gross lift: .595 .600


duration @ .050: .232 .236

110LSA

If you need any other info on the cam let me know.

I'm going with crane duals and TI retainers with my set up. I think the springs are good for 640 lift. I hope this helps.
