Why choose matched valve springs for performance cams?
Spring pressure must match the cam profile and rpm limit. Too little causes valve float; too much causes wear.
Do I need adjustable cam gears?
They allow fine-tuning of cam timing, especially useful after head machining or when running non-standard cams.
