Thought I throw this in the mix. I am running Hooker Competition Headers on my 302. I took them to a ceramic/powder coating place, told them I wanted ceramic coating (after seeing a friend's ceramic coated headers on his Cuda) and when I picked them up they looked powder coated, rough surface and not smooth. The guy insisted they were ceramic coated but they were not, I should have just left them there but paid the $250 they were asking!
