Should be a few threads on this in the Archives, but:
I've used Eastwood's high-temp stainless paint on manifolds and headers, lasts pretty much forever. Gotta start with an absolutely clean surface, and bake it, which an engine does quite well. I'm glad to hear this, I just used Eastwood on mine.

That's exactly what I did. I used the product Slip Plate, a graphite spray lube. I did my exhaust manifolds in February. They still look great. Came out much better than the cast blast. I bought it at Grainger. However, I read that Napa sells it too. https://www.grainger.com/product/1WVK7?gclid=EAIaIQobChMI-8mdxsWU7AIVATiGCh3djASPEAQYAiABEgIKmPD_BwE&cm_mmc=PPC:+Google+PLA&ef_id=EAIaIQobChMI-8mdxsWU7AIVATiGCh3djASPEAQYAiABEgIKmPD_BwE:G:s&s_kwcid=AL!2966!3!281698275537!!!g!472123448796!&gucid=N:N:PS:Paid:GGL:CSM-2295:4YUPY8:20500731

Hey guys, thanks for all the replys! They all sound like viable avenues. My only question with the liquid graphite is that, once it dries, does it turn powdery and does it fly around like powdered graphite does?

When slip plate is put on, it's rubbed on and buffed so it works it's way into the pores of the cast iron.

That's cool. All I could picture was graphite powder floating all over the engine bay after it dried out. Thanks! Here is a pic of the exhaust manifold with Slip Plate. You can see how Slip Plate gets into the pores. There is no issue of graphite powder floating all on the engine bay. This is done by spraying and letting it dry for about a day. Then, take a soft cloth or shop towel and buff the surface. As you see, there is no powder residue or flaking.

I put it on once so far. Have not touched it up yet. If any parts do wear; you can simply spray on the manifold, let dry and buff or spray some on a sponge brush and sponge it on, then buff. It gets into the pores much better than paint will, so it will last..
