I hope this lets me post, I;ve been having a heck of a time with the site for the last week.
Norm most of the big dodge trucks that had Hemis in them use the 331 or 354 (as far as I know they never put a 392 in a truck or industerial application). These engines will have valve covers marked "Chrysler Industeral" on them an have the dimples for adjustable rocker arms (although all of those I have taken apart actually had hydraulic cams and non-adjustable valve trains. The are usually not marked on the front vally pan rail, but may have a brass tag on rivited to the bellhousing area.
Just a thought, if you can;t find a decent priced 354 or 392 I wouldn;t necesssarly turn my nose up at a 331. her are just a bit bigger than the 325, but have a lot better aftermarket support. In the long run it may be a better option than hunting up heads for the 325.

".......No telling what I will find as it seems ALL early hemis are 392's if you know what I mean....."
Yup just like every small block chevy engine that someone is selling came out of a Corvette.

regarding the 331, make sure you don't pickup one of the extended block ones. I don't think anyone makes an adapter to put any other trans on it.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Sounds like you did your research already. If they are the "triple 5" heads they are suppose to have a better port configuration than the stock 392 heads, but as you say they will require spacers.
The other option would be something like the old Weian Dragstar 2 piece intake, unfortunately I don't believe the hood would close LOL.
You also want to make sure you get a 57-58 392 HEMI oil pan. as it's the only one that will fit.....the 392 is center sump and looks like the one on the 325 in the car, while the 56 and earlier pans were rear sump.
Edit, I missed your post about getting the engine this morning. The adapter sounds cool, it opens up some more trans options for you. Too bad you aren't closer, I happen to have a 63 or 64 BB pushbutton trans.

The heads you have would be the triple 5s. Unfortunately the 325 pan won't interchange, however I wouldn't be surprised of you could get more for the custom pan (if you can determine the application) than a stock pan will cost. I think Hot heads carries the correct pickup tube to go with the stock pan.

Ok, as far as Transmissions go, the cast iron TF in the dodge will bolt right up to the 392.
A later aluminum SB 727/904/518 will require an adapter, which includes a flex plate, spacer plate and adapter to get all the spacings right.
An 833 style 4 speed can be used with either a commercial adapter custom Flywheel. An adapter can also be fabricate using a modified stock Hemi/poly spacer plate, and cut down Hemi or Poly flywheel.
I'm not sure what the BB 727 adapter you have requires, but would sure like to see some pictures of it.
