You would never 3D print one, you would CNC machine.
Some guy was just on Facebook the other day hawking one. I would expect to pay about $1000 for a nice one. And good luck finding one for sale.  I would reconsider which head to use, but would also encourage you to "join back"!

There is one currently for sale on Facebook but not sure which group or whether it's in the general Marketplace. It just appeared there yesterday but I cannot locate it now so maybe it got snapped up. I may have one for sale soon too but it's not perfect, having a little previously-repaired corrosion under the outlet but the spark plug holes and outlet holes were all Heli-Coiled years ago. As the head was 1954 senior model only, there were no variations.

I found the Facebook listing but you'll need to be a member of the Packard Automobile Classics group to view it.

It sounds like the guy is willing to take 500 bucks for it, but it will need to be checked over at a machine shop before it goes on the car.
There's another guy that commented saying that he owns three of them, but who knows what kind of condition those are in.

Thank you everyone
Excluding corrosion or some kind of damage, was the aluminum cylinder head inherently faulty or a problem area? I ask since I see in my research many advise it is better to swap out to the steel cylinder head and skip the aluminum cylinder head I only had one part made by 3-D printing but it was plastic so . . . Has anyone heard of someone using two horizontal slabs of aluminum and trying to replicate one? Conceptually it doesn’t sound impossible, especially with AI and computers. This would assume a junk one could be sourced and sawed in half horizontally. I know it sounds easy until you try finding someone willing to give it a try

Then maybe time to join! Otherwise you're leaving out some major resources.

Maybe I'm missing something but why would you need two different slabs of aluminum? Aren't they machined out of one solid piece of aluminum? And yes, you are essentially correct in that you could 3D scan one along with some metrological investigation and/or purchase the factory drawing and get a new one machined however, I doubt it would be any cheaper than just buying one.

Pretty sure they are cast. Remember that they are hollow on the inside with water passages. No way to machine those passages that I'm aware of.
There is an outfit somewhere that remakes old blocks through a complicated process. They cut the block into thin slices, 3D scan them, then reconstruct the block digitally. Then they 3D print the block in a castable resin, sand mold it, burn it out, and then cast it in iron. The process is prohibitively expensive. My dad was briefly looking into it when we were having nothing but problems with our '38 Super 8 block. But it's a pretty penny.
