Exhaust manifold recommendations

This is the one I would buy, very specifically, but there's no single right answer; you've got options:

• Buy a used one: spend less money, but you have to hope you get one that isn't warped, cracked, or otherwise faulty. Hope it stays that way.

• Buy a cheaper-than-Dorman new one: spend middle money, but you will likely have to contend with relatively poor casting quality and accuracy. Makes it a pain to install, too.

• Buy a Dorman new one: spend more money, but "done in one" and you can move on to thinking about things other than exhaust manifolds.

All the aftermarket exhaust manifolds, regardless of brand, are made in China. Whether they all come from the same factory is unknown; it is extremely difficult to chase parts back to their actual origin in China. Dorman is a reputable vendor. Quality of the aftermarket manifolds is generally not quite as good as an original Chrysler manifold, but the best of the aftermarket units are fine. They are NOT all alike; one thing that is very easy to see in the Chinese parts supply stream is stratification: the best castings made into the best manifolds get sold through the premium brands at a relatively higher price. The not-as-good castings made into not-as-good manifolds get sold to 2nd-line brands at a somewhat lower price. And so on and on down the line; only the really completely nasty, totally unusable castings get scrapped. Unless you happen to get lucky, you don't get what you don't pay for.

It is very much worth your while to get the good gaskets for the manifolds-to-head and intake-to-exhaust junctions.

Also, note that all the replacement manifolds are the '73-up type, which will not take the '67 choke thermostat. Assuming you're running a 1bbl, put on a № 1231 Electric choke kit to neatly solve the problem without creating new ones.

Of course, you could also zoot things up with Dutra Duals.

(Super Six 2bbl setup is a separate question completely; the exhaust manifold is not different.)
