If the manifold is a reproduction I would say go ahead and put new porcelain on it, but I would hesitate to do that to an original because I have seen them warp and crack into pieces. So unless the car is a trailer only case there is a very high risk of complications.

The 833 and 840 exhaust manifold are the most robust of the two piece systems, but nobody is deducting anymore for high temperature powder coat so I would do that rather than the porcelain route.
