Very good advice. Filing just ten thousandths of an inch off will give you several more valve adjustments. If you're not confident about doing this, I'm sure a machine shop would grind off ten or twenty thousandths for you cheaply. But it doesn't need to be precision work, since that surface doesn't actually contact anything.
