I believe from the factory to make them look "most correct" you would just paint them engine color and then let it burn off. But unless you are going for 100% correct I would go with the cast iron gray paint from Eastwood.

Coverage wasn't specific, they were just in the way of painting the engine so they got doused pretty good. Most burned off in a short time but some usually remained around the port flanges and bolts.

True. That said, I've had good luck with having the manifolds treated with high-temp ceramic coating, which is available in an authentic cast-iron colour. It lasts infinitely longer and is not susceptible to the fingerprints and such that can affect the Eastwood paint (DAMHIK ). Note: that is not a bash of the Eastwood paint as it is a nice product. However, you do need to be careful not to contaminate the surface. A quality shop should be able to do it in such a manner that it doesn't significantly affect the texture and appearance of the base metal. If you're going for OE certification, then bare metal is the only way.... Last edited by YYZ; 07/07/13 07:23 PM.

Thanks If "correct" is what you want, then rust is what you'll need as factory manifolds had no protective coating, engine paint overspray was about it, and it didn't last long, so they ended up looking ugly in short time,...IMHO, if your castings are very nice and pit free, I'd have them ceramic coated, Fireball coatings does a very nice job, they have a very natural coating for a new cast look, you can then decide if you want to add the "overspray" appearance to them for a much more original appearance, I've used Fireball coatings after Alan Galant (barrelcuda) recommended them to me, and they're right in your backyard in Erin, Ontario, a set of manifolds will run $250-$350 depending on size, do them once, do them right Mike Fireball Coatings 519-833-2628

Yes, I will add another vote for Fireball Coatings - that is whom I have used and will continue to use. At one time they used to have dropoff locations in the Toronto area and elsewhere so one wouldn't have to trek up to Shelburne. Now that they're in Erin it's a bit easier to get to.

Pre-'70s don't have them. Yes, you are right. 383 & 440 4-bbl applications for '70-'71 had the heat stove on the DS manifold. If the car were equipped with a shaker hood, Air grabber or Ramcharger, then the heat stove was omitted.
