Wow! That really is a deal, there was a VR57 Supercharger and carb bonnet that went for $4995 on ebay early this summer, with out the heads, intake, carb, distributor, fuel pump or filter.  Granted they don't all go that high.  You really did get a deal!!!  

Nice collection of F parts, they all look correct, I am surprised at the date code on one head showing it was made in '58.  Is it possibly a service part?

Thanks, I am surprised as well.  I have quite a history working with metal and as far as I can discern there is no evidence of tampering which leaves (in my mind) three possibilities: 
1) it is a service part  ( but it does not have the "S" that would typically indicating this)
2) It is possible that an operator transposed the 87 (possibly should be a 78) 
3) Or..... and this is a shot in the dark.... I have absolutely no clue.  

I really would like as much input as possible from the community.  I am having a hard time putting my finger on this one.  Who are the recognized experts on F-Code cars?  

Frank Rice aka Pegleg and Richard Stuck. Just wait a while and they will answer as they come and see your post...

John Mummert's web site at  http://www.ford-y-block.com/  has some insightful information regarding y-block cylinder heads.
John indicates that beginning in May of 1957, FoMoCo y-block cylinder head castings were modified.  This was well into the '57 model year production run.  The modification was the adding of 'posts' to the heads to increase their strength above the piston.

In the book, Ford Y-Block by James Eickman [1984, MBI Publishing Company] in talking about the '57 early EDB-D production supercharger cylinder heads, Eickman states that they, "...would sometimes fail in competition use.  The roof of the combustion chamber would lift as a result of the high combustion pressures".

Based upon J.M.'s information, the following 1957 FoMoCo cylinder heads may or may not be 'posted' DEPENDING UPON WHEN THEY WERE PRODUCED:

-  ECZ-G casting letters - LARGE letter series  [these were used on 272, 292, and some 312s]
-  EDB-D and EDB-E (these were used only on 312 supercharged engines]

ALSO, although used in '57 production Ford vehicles, NONE of the following were posted regardless of casting date:
-  ECZ-G casting letters - SMALL letter series [these were used on 272, 292, and some 312s, but no 'C', 'D' or 'E' code '57 'Birds]
    The small letter ECZ-G heads were cast in Dearborn

See Tim McMaster's web site at  http://yblockguy.com/techtips/postedheads.html  for clarification on cylinder head 'posting'.

I'd have to say they're worth ever bit of 4300. The intake is valuable as well as the carb. Those parts are all unique to the F code cars.
  there were only roughly 1200 or so ever sold, 57 years ago!. Nobody knows how many still exist but it is certainly very few real ones.

You've got to determine what you've got parts-wise.  The original '57 passenger car supercharged engine would not go into the 'Bird you've purchased.  Assuming that 'Bird style components were used to install the engine, you've got to determine if they are original Ford replacement components or later non-Ford reproductions. 

Presently, (today) for 'F' code 'Bird applications...
- new (reproduction) air cleaner housings are being made and sold,
- reproduction bracketry has been available in the past...some in aluminum, some in cast iron,
- new (reproduction) 'Bird standard transmission and automatic transmission crankshaft front dampers are available for sale
- original 'Bird tach drive distributors can be re-fitted with re-worked distributor plates to mount dual points per original, re-stamped to display the 'Bird S.C. i.d. number (only the suffix letter has to be changed).  I don't think that original spec S.C. distributor springs, distributor cams, and vacuum advance chambers are being installed in these clones.
_____________________
What's are the parts worth?  To the person who is restoring a true 'F' 'Bird or 'F' passenger car, who is missing these parts...IF the parts ARE original and IF the parts have production dates, it becomes important that the dates on the parts are pre the production date of the car being restored.  IF all the info. fits, the parts can bring t-o-p dollar from that buyer.
 
For someone who is building a clone for nostalgia purposes or sanctioned racing, they still may pay a serious dollar, but not as much as the individual building a numbers-matching museum type car.

IF I were looking to sell what you have, I would contact someone who has dealt with this stuff extensively and KNOWS what they're looking at and WHO they might turn to for a sale that would be related to the restoration of a high end car.  The following individuals KNOW '57 Ford supercharged engine parts and assemblies.

Just as an FYI I struck a deal to sell the two heads intake and Carb for $7500. I will be delivering the parts to him at about 10am today. With that I have one other person offering $8,000 but I am sticking with the first buyer as he has been helpful to me in the past. All of the parts are in the condition they were in when I pulled them.

I just wanted to let you guys know what they went for, thanks for all of the help!

While it’s not impossible that the first two digits are transposed, it’s unlikely.  Even transposed, it puts the two heads being made two months apart making at least one of the heads not being a member of the original pair.  It’s possible neither head is original to the other ‘F’ parts considering how many of the early supercharged heads initially cracked.  For now I’ll go with the 1958 head simply being a replacement head.  You might check to see if both heads are posted or not as that may be another clue as the 1957 head could possibly be unposted and the 1958 head is.  Don’t let the date codes deter from the fact that both heads are the EDB-D heads and having a significant spread in the date codes is not going to be a detriment to their value.

Here’s a link to an older thread on how to identify posted heads.
