What is the difference between roller valve springs compared to regular valve springs? I am assuming these are only to be used with roller camshafts but why? Why could you not use them on tappet cams or vice versa?

roller springs are stiffer to follow the quick open and close profile of a roller cam if you use them on a flat tappet cam you'll ruin the lobes. if you use regular springs on a roller cam you'll float the valves.
