Calculate Torque Required to Turn Cam

" I was taught that the only power taken away from an engine due to the installation of heavier valve springs (very little) was due to extra friction/heat created. Valves being pushed down, and others returning should cancel themselves out..
Plus flat tappet and roller cams exist if that makes any difference in the power required. I'm a CS student so.. I'm not sure how specific calculations would have to be."
