I've heard that there are factory aluminum intakes in both 1 + 2 bbl. Is this true? I've never seen one.

Yup, sho nuff. I know some of the aluminum two barrel ones had problems leaking vacuum between the casting halves. I don't know enough about which ones to look out for. Maybe slantsixdan will chime in. He's real sharp about them.

Yes this is true, and they also came in aluminum too which turned out to be very porous and vac leak on some.
They also made 1 brls in aluminum.
If you apply a very thick number of coats of engine paint to the aluminum versions they should have no issue, I would think.

Sounds like a great candidate for a powder coat job by the mistress of metal

I know I'm right....
that is the recommended procedure over on Slant6.org, they should just put CudaChick1968 as the link for the powdercoating. I heard many went back to the dealer and got swapped out for iron ones.

Sorry...But I just wanted to say "Kittypancake".
Me too Johnny! That's been cracking me up ever since I first saw it. Great name!
There is actually a one piece aluminum intake use on cars and a two piece intake used on alot of later model trucks the two piece ones are the one that leaked. I believe I have a couple of the two piece ones at the house and I knowe I have a one piece at the house.

I had my chance to buy one brand new from the dealer in '98 but passed it up to save $$$ and ended up running the iron piece I already had.
Just the cam/lifters & full length header i bought from the dealer was over $600

I have a stock 1bbl aluminum intake I can sell if anyone wants it. Was going to use it before I ran into a deal on a super six.

I have no idea why the photo links started displaying like this,, but it works, click on the text
scroll across the photos, there is a close up of the joint lines on the factory cast 2 piece intakes, the joint lines on the face would be sealed by the mounting gasket,, the joint lines on the exterior can be sealed with paint as mentioned previously.
On the M-1 intake,,the attachments are throttle brackets of some sort that were put on by the previous owner, bolted on to the EGR mounting area, left it on till I get ready to use it

the m1 is just a better casting of the factory version....and costed around 279.00 when they were offered.

=..=
1960 slant-6s all had aluminum 1bbl intakes. Some were sandcast, some were semipermanent-mould. No EGR or PCV provision.
The next factory aluminum intake (not counting the Hyper Pak item) was a sandcast aluminum 1bbl with EGR and PCV provisions on the 1976 Feather Duster and Dart Lite.
After that came the 2-piece electron beam welded ultralightweight aluminum 1bbl and 2bbl intakes starting in '78. The welds are ugly and can be porous, and the casting has so little mass that it's prone to floor cracking due to thermal cycling. But if you get a good one and prep/seal it carefully it'll work well and warm up almost instantly. EGR, no PCV (by then, the PCV outlet and TAC vacuum takeoff had been moved to the carb throttle body so the 1/4" hole in the carb mount flange wasn't needed any more).
After that came the 1-piece sandcast aluminum 1bbl in about '84. Not sure if there was a factory 2bbl version of this, but the Mopar Performance M1 was essentially a 2bbl version of it. Sandcast, 1 piece, with EGR provision.
There have been a lot of aftermarket aluminum intakes for the slant-6. Offenhauser has since 1961 made dual-1bbl and single-4bbl units. Weiand made a 4bbl. Lynx, Warneford, and another outfit I forget at the moment made twin and/or triple SU sidedraft intakes. Cain and Speco in Australia made various intakes. Penìn in Argentina made a righteous parallel single 2bbl item. And then there were these long-runner twin 2bbl items originally used with Weber downdraft 2bbls:
And this mindboggling 4bbl that looks as if it would solve a lot of mixture distribution issues with other 4bbl intakes:
And how 'bout a dual-carb, dual-plane intake for a slant-6:
