When changing cams do I need to upgrade valve springs?

Are the Andrews 420 cams going to raise the performance of my 2021 Scout?
Answer QuestionThese cams will work with all OEM Indian Scout valvetrain components. It's a direct swap - no special parts are required. You'll notice a bump in torque, mostly between 1,800-6,500 RPM. The 420 grind cams are a really good all-around design.
