I was looking at some of the vendors on here and could not see any that carry stock manifold for our Slant's. Who do ya'all like as a reliable source? I saw on Rock Auto, Ebay, and another source but was concerned they are cast in China. Is the Dorman brand still made here in the US? Sorry for so many questions but I figured since I'm into this fuel injection upgrade I may as well slap a new exhaust manifold on this engine.
Thanks!!

Yes, they are.
It never was. However, it is the best quality option presently available. As you can see, the Dorman item is more expensive than the "same" manifold—see Joshie225's link—from other companies. The reason is simple, you (don't) get what you (don't) pay for.

Thanks for all the info! I'm checking everything out especially the Remline gaskets. I believe I'm going to go with the Offenhauser manifold if I can get Dan the guy from N. Georgia to get back with me. Let me ask one more question because not asking questions is what took me down the wrong path. It is my understanding the Offenhauser manifold will mate up to the stock slant exhaust manifold is that correct. If I put a block off plate over the stove portion of the manifold will I still be able to mate the two manifolds up?
Thanks everyone!!

Yes.
No, and that would be a bad idea even if you could.

Could you share why that would be a bad idea. I will be using a FI throttle body from a company called FiTech and not a carburetor.

Throttle-body injection like that is still a wet-manifold system, and still wants manifold heat for all the same reasons a carbureted system wants it. Only with port fuel injection would you want to look at eliminating intake manifold heat. This 1935 Jam Handy cartoon, "Down the Gasoline Trail", would be a real trip to watch even if it didn't contain a sequence specifically answering this question about the manifold heat (at 5:37).

Thanks Dan, I have decided to get a new Dorman manifold from Rock Auto using the code from this site the 5% discount will pay for shipping. I'm heading to North Georgia this weekend to trade my Clifford for an Offenhauser. Can't wait to hear this truck fire up with the new FI. Also the Remline gaskets you mentioned in a previous post is the vendor advertise on here. I was looking at the parts source list and did not see them listed. I also enjoyed your video. Really funny how things back then were so much simpler. Maybe not to them but we see it that way now.
Thanks Again

You're probably thinking Remflex and not Remline

Remflex gaskets can be purchased from their site here:

http://catalog.remflex.com/category_s/87.htm

Or on amazon here:

Thank you for correcting me JBracey. I would have been searching on Remline trying to figure out why they didn't have gaskets! Lol
