Edelbrock heads and cam break in

Looking for some opinions. Should I be putting some weak stock springs in my heads for cam break in? The seat pressure is 120, and they are a single spring. Open pressure is 320. I'm going to run stock rockers for the break in. Cam is a Voodoo 200703, exhaust lift is highest at .513. I have comp cams additive, and rotella 15w40 to put in. I've got the run down on the procedure for start up.
