If you're a serious racer, you'd better be sure that you're using strong valve spring retainers, such as these AFR titanium retainers. They're stronger and lighter than steel, which means that you'll gain speed and power. They are designed for 10 degree valve stem locks. These retainers work best with AFR valve locks and optional lash caps, and you can be sure that they won't split at high rpm, tearing up your engine.
