Honestly I'm not sure what a fair price is. I'm seeing prices all over the place, that's why I was asking about part numbers and value and "date code" value.
Maybe you can PM me after you figure out shipping price and we can talk a price that would be fair for both of us.

The market will dictate the value only after a full description is provided. As another guy said, 461's and 462's were used on many different years and HP 327's. I suggest you do some research on what they are going for and in what condition. Then, provide a description, 202/194's screw-in studs, recent valve job, good guides, etc. all in the same post or ad. Then state an asking price. There are people just looking for a good set of heads, there are some looking for date specific for a restoration. If they're just something you have and don't know the condition, $200 sounds about right per pair. If someone is looking for a specific date code, they'll pay a little more.
Good Luck,

I have two sets of heads that I have had for a while and I want to see what they are from and what they are worth.
The first set of heads I believe are camel hump heads with no accessory holes and the markings include:
3782461 and 3782461
H21 1 H26 1
I think the dates are 8/21/61 and 8/26/61
-------------------------------------------------------------
The second set of heads I believe are camel hump heads with no accessory holes and the marking include:
3890462 and 3890462
C3 7 C3 7
I think the dates are 3/3/67
So how can I find out what these heads cam off of and what they are worth? Can someone fill me in or point me in the right direction?

461 "X" heads were reportedly found on a very large number of trucks, as well as various full sized Chevies. They were used for 327/300 horsepower engine as well as L76 and L84.
Racers once paid a premium for them, but no longer true today. If you get lucky, then you MIGHT find a pure stocker willing to pay a premium for them. I can tell you from experience, that a pair of ordinary 461's will port out to the same intake port volume as an "X" head. The 461 "X" head was cast with 170 cc intake ports. The ordinary 461 was cast with 160 cc intake port volume. I have ported ordinary 461 heads to 182 cc intake ports, which can support about 430 flywheel horsepower.

You are correct on the dates and these heads are 461X indicated by the single year digit. They were used on 1962 Corvettes with fuel injection 327/360hp (Only). I'd keep these puppies!

Correct and since the heads are dated as H21 1 and H26 1, they are Flint heads, correct for a Corvette. The Tonawanda (sp?) heads would read like this H21 61 and H26 61.

According to Chevy by the Numbers the 461 heads are from 64-early 66, 327 300 hp and up. They could have either the 1.94 or the 2.02 intake valves.
The 462's fit late 66 327 and early 67 327, 302 and 350, 275 - 350 hp.
I can't help you with value, check ebay, hemmings and other sites for some help.

The casting number means nothing....they could come in any configuration.....
They are both worth about the same.....E-Bay right now machined and complete they go about $600.
Castings...used about $250 a pair.
The 461X is the only big standout....I am a little fuzzy here....but I believe those were 62 F.I. only heads.....the only difference was the port is about 10cc's bigger at 175cc.....they command north of 1K on Greed-Bay
Ooops...just read where this info on the X head has been posted...oh well!

The X goes with the years casted. ALL 461 Flint heads for 61. 62, and 63 were "X" castings and used on all 300 up hp 327s. The X dissappeared in 64. Not sure if T castings had the x or not.

My sources indicate all 461 "x" heads were reserved for the fuel injection option only and ended in 1964 as the last fuelie head was made for the production 1965. I suppose definition depends on quality of resources. That will be the final factor, as there are many resources to choose from. I have quoted Nolan a few times retracting my statements as his book “Bible” was revised. So what is limiting this from reoccurring again? Seems like new information becomes available every year…. If there is someone who has a paragraph and a quote dated, and it is recent I will concur.
Hey we are only as good as our recent resources tell us right!

bringing this back from the dead
I posted about these cylinder heads back in 2012. I recently started going through some of my parts and came across them again. I took some pictures this time. I've been searching the forum and ebay to figure out a fair price to sell them for.

Those casting numbers are the same as my 62 vette. They did come on many early 327-300's, but believe the year range 1962-1965. Those are August 1961 built heads, so anyone with a September built engine is right on and maybe even up into an early October build. My heads were built on 11-24-1961 and the engine built 12-13-61. Not a very large window between casting dates and engine build date.

The first set are the original big port "fuel injection" 461X heads that were first used on both FI engines in '61 and 300/340/360 HP engines for '62 and '63. They are cast iron versions of the ill-fated '60 aluminum heads. For those three years they were only OE machined for 1.94/1.5" valves, but have about 10 cc greater inlet port diameter than later heads.
The "X" is embedded in the bottom of the casting near the water outlet.

The first sets looks to have 2.02" valves, but the chamber doesn't look relieved to allow the larger valve to breath.

These 1961 vintage 461 heads also do NOT have the "X" on the block side. They appear to be regular port size 461 heads. The 461 heads have been modified with 2.02 intake valves and screw in rocker arm studs. They look good, but disassembly and a date with magnaflux and a light to check for cracks would be needed to establish a value equal to the prior 2012 estimate range.
The 462 heads look more original with 300hp size valves and pressed in studs. The same crack inspection applies to verify the value.
Since 2012, Trick Flow released aluminum heads that externally look like these 461/462 castings, but they flow much better and handle heat & detonation better. The cost to modify these iron heads to the performance and condition of the new Trick Flow heads is more than the TF heads cost. The result is the performance and appearance based value of these old iron heads is dropping fast. Unless you find someone who wants date coded heads for their car, the value is less than the 2012 estimates (and head dates and internal identifiers under the valve covers are not judged, so that continued demand is speculation).
.
The valve covers are from the late 63 to early 66 range, after the mold casting flaw line started to appear but before the mold damage increased to start closing the "o."
Since 2012, repop valve covers have come into the market. The repop's are very course finish castings compared to those in the photos, so the original covers are still worth more than the repop's (check pricing on f-bay).
I expect some of this is not what you hoped to hear, and it is an example of a market where reproductions are a better product (the heads), and one where the reproductions are inferior (the valve covers).
