Is it possible to paint iron cylinder heads and have the paint stay on. I do not want to take the heads off the engine, but I have the engine pulled out of the vehicle. Most paint I’ve found that does not have to be baked, is rated for 500 deg. (probably not enough). I’m also painting the block with the 500 deg. paint in gloss black and would like to paint the heads with gloss black also. Any suggestions would be appreciated.
