Cylinder Head ID Help!

I have a set of FE cylinder heads that I want to make sure they are 428 or 390 before I sell them.

#C6AEU #inside by the valve springs is 6E24.

Early 14-bolt 390GT heads, have some value as they are correct for '66 390GT/GTA vehicles which were all shock tower cars, hence the 14-bolt exhaust pattern. GT heads are unique in that the two top end exhaust bolts are lower than the center ones, and they don't have the bottom two center holes like a 16-bolt CJ head. Poor choice for a pickup engine, as the exhaust ports are the "low" version and don't match with many of the pickup manifolds/headers

They're worth whatever someone will pay you for them. And what's been done to them also determines the value. As for they won't work on pickups, the bolt pattern is not a problem to fix when run with headers. I ran a 67 GT390 in a 70 F100 with Blackjack headers with no problems. A little work on the header flanges will make things right.

"Poor choice for a pickup engine" and "they won't work on pickups" aren't even close to the same thing, unless it's just "spin" to create drama. Enough said on that

They are still a poor choice for a pickup, or anything else for that matter, not a particularly good-running head, not bad but nothing special, and worth more to someone for a "correct" vehicle- if you found the right person who's looking for them, they're worth whatever they will pay for them, and might make a good down payment on some Ebocks. IMHO not worth the trouble to try and make mediocre heads "work"
The PO of my 390IP '69 Ranchero GT actually took a hacksaw and cut a slot out of the exhaust flanges of the end ports to bolt up a set of Hookers- ruined the heads, and they still didn't line up right as the headers are made for the higher port of a CJ, which also has all the bolts in a straight line. Of course, the same guy also ran a DA sander over the data plate on the driver's door and ground it flat...

Ok, Gene, we're well aware of your "experience" here. By the way, I'm STILL waiting on you to tell us why a 3x2 can't be tuned to work as well as a single or 2x4. What the PO of your Ranchero did is also irrellevant as it's a car chassis and those are car headers, it may look like a pickup, but it's not a pickup.

Well, as once again you live to argue, and will spin things whatever direction it takes to create some drama, the "relevance" is that those particular Fairlane Hookers are designed for the CJ, which has the original-style higher port, and do not fit the GT head correctly even with the end holes re-aligned, just like your average pickup head- same problem in another vehicle. Not worth the trouble trying to make a mediocre-running head fit where it doesn't belong when one can just use heads that fit correctly- and probably run better
Bye now- save your usual "witty" retorts, not interested
