IMO oem valves are very good and i wouldn't change them for anything else.
As for the springs and retainers just go with the same brand as the camshafts.
IMO if money is not problem JUN type 3 with JUN valve springs and type 2 retainers just like my head :naughty:
No other cam will make more peak power.
Toda if you want a track machine with more mid range :nice:
