oki so i have a friend that has some blox stage 3 na cams and he wants to trade me for my ITR cams. i was wondering if i could possibly run these blox cams with stock springs and retainers or will it just not work?

and also i would like to know where could i go to buy a decent set of valve springs and retainers and valves if i need them. or what you guys recommend me buying to run these cams or should i just keep mines?? thanks guy any help would be greatly appreciated!
