I know enough about FEs to be dangerous could you give me some areas to look at to see why the were discarded,they are still together and there is nothing obvious --broken springs,cracks or burnt valves in fact the look fairly fresh--clean paint and not a lot of carbon in the chambers.I am going to pull them apart to check the guides but how do I tell if the seats a recessed to far as to be usable and if they are would these castings be worth putting new seats in them.These heads are for a 75 F-350 2x dumptruck. Thanks for your response.

You may find the valve guides to be extremely worn. A good machinist will be able to give you the precise condition. Even good pictures won't help anybody find small cracks or detect warpage. They did not come with hardened seats from the factory so you may have to have them installed. They are a good head but figure out what it takes to get them rebuilt properly. It may not be worth it depending in their condition. It was going to cost me about $900 to get mine rebuilt right. I went for the edelbrocks.

in 73 i believe they went to hardened seets in all of them due to emissions and it cost me $288 to get my 390 heads redone, new seets, guides, magna fluxed, hot tanked, milled .10 new valves were about $75 so its not cheap to rebuild old heads.

Just to throw my info in the ring here, I have those same heads on my engine, and with just some basic porting, new exhaust valves,valve guides, and hardened seats, it was roundabout $500 to get em done. They work great, and I only wish i had the time and money to get more exhaust flow out of them with headers.

I have a set of those.
Im using them now at the moment...
But I had good valves and such in them
I cleaned them up, ported them, springs were still good, etc
My motor had been rebuild 5 years before I got it
But it sat those 5 years, just started occasionally
So I got mine pretty cheap

I think he means, he needs headers to utilize the extra flow from the port work. I think even without port work, you need headers. 
Also, the hard seats were installed due to falling lead content of gas in the mid '70's, it doesn't affect the emissions that I'm aware of. Could be mistaken.

Yes headers are a must with any FE. Unless your's was blessed with the factory cast iron banana pipes
