If you want porcelain. In time (starting 15 years?) it will start micro-cracks, from heating and cooling, then chip off. It's glass. Just look at an original porcelain Packard, Duesenberg, or Jaguar manifold. If it was porcelain originally, then I think you'd want porcelain.

If it wasn't porcelain originally, then ceramic coatings that retain the original look of cast iron or a painted cast iron manifold are the way to go. They help dissipate heat and keep the manifolds looking like brand new with no maintenance. There are different finishes and colors, matte and glossy (extra due to polishing), but $160 for a pair of manifolds is a great investment.
