I picked up a used rebuilt 390 to put in my F350 and found out the heads are 14 bolt pattern. The casting # is C7AE-A which is suppose to be bigger valves I believe. My question is are these heads GT or better than stock. I can't find any exhaust manifolds to use with the 14 bolt pattern. Do you think I could trade anybody for a pair of stock 390 heads like D2TE AA just so I can get this engine installed in my truck. I have my old engine, with the stock heads, but was going to sell it for a core to recoup some of my cost for the rebuilt engine. I am trying to go the least expensive route. Any suggestions or options are greatly appreciated.
I've got a set of D2TE-AA. I'll trade if you want. Mine came out of a '72 F100. They'll need to be reworked and checked over and I think they have a couple of broken exhaust bolts that your machinist can remove.
The 14 bolt heads are for a GT motor (usually). I think they were made for the Mustangs, Torinos and others that had the old shock towers in the way of the exhaust manifold.

Barry, those look exactly like my heads. Interesting. I am suppose to meet with a guy tomorrow about possibly exchanging my heads for some stock 390 heads with about 3K miles on them. I guess if it doesn't pan out I could put them on Ebay or contact the other bidders that lost and see if someone is interested in picking them up. Thanks for all the help. I really do appreciate it.
