Good afternoon Greetings .. I need to know how much pressure springs need some cams GSC STAGE # 2 to work properly

 

id say about 2 tons.

 

This came directly from GSC web site " The S2 Cams are suggest to run on our upgraded Beehive valve spring replacement or can be run at the stock revlimit and factory boost on the stock spring "

You can run springs made by other companies, The website i mentioned above will give you the pressure rates.
