I'm not an expert so i won't attempt to give you advice on what the best springs are to use on the roller cam you have chosen.
You could go to the main page here and get the contact info for some of the vendors that build engines and sell roller cam setups and see what they reccommend for your cam. I'm sure DLS, Fullthrottlespeed, Weber racing just to mention a few can help you make the right choice.
I used the beehive springs with my 214/214 comp roller cam after searching around and seeing what others were using with success.
Hope this helps in some way and good luck with your new engine.
