This might sound kinda weird, but you might want to keep the stock valve springs. (IMO)
The valve train is solely dependent on the cam for maximum performance. Whatever the cam calls for, that is what you should install (lifters, push rods, rockers, springs). If you don't want to keep the stock springs, I would recomend getting the stock replacements from Comp Cam's or Crane.
I would imagine someone else would differ in opinion then me but I am learing just like you
