I've heard good things about muriatic acid, although I've never used it. I guess it's the same stuff they use in Vaseline. My go-to stuff is phosphoric acid. Same basic routine. Soak the parts in a tub, and keep turning the parts to get everything soaked off. Don't use it on aluminum, though; it will eat it up (yum, yum). You can get a one-gallon jug at Home Depot for about $16. If I have the time, I'll set up an electrolysis vat for a few days, then I'll attack the parts with the acid and a wire brush.

The acid is used for etching cement, so if you spill/splash it on your driveway and don't clean it up, you may have interesting designs ...

Beware of Thunderbird intakes. The carb sits flat on them, as in parallel to the valve cover. This may or may not cause an issue with float level in anything but a T bird where the engines sit parallel to the ground. Worst case you could have a spacer fly cut at an angle to compensate, of course you'd have to open up the stud holes too.
