What it does

Valve springs close the valve and keep the lifter on the lobe. Tired springs float valves at high rpm and break under aggressive cams. A matched spring kit with the right installed height, seat pressure and retainers is required for any cam swap and cures high-rpm misfire on a high-mileage engine.
