I red something about to use only stock springs to brake-in a new cam.
I don't know if I need to change the springs in my heads ( AFR 195cc street heads) for cam break-in. Since I don't know much about valve spring pressure, I copy this from AFR's site, to give you some idea about what i have; "1.450" OD Hydraulic dual valve spring w/ dampener, 120lbs on seat, .550" maximum lift"
Is realy necessary to change my springs for stock ones?
I would like to know what you all think about?
