051 headers

Found a set of headers in a boneyard today that were laying in the engine comp. of a 71 F-100. The owner says he's pretty sure they are 360-390 headers. but not sure about the exact application. The only markings I can find are near the collector and are "051".
Any ideas on this one? Maybe someone has seen this before.

take a couple pieces of paper ,tape them together , lay it on the flange where they bolt to the heads and use a pencil or chalk to get a rub or outline of the flange. then just set it up against the engine you are wanting to use them on and see if it matches.

if the bolt holes are on the top and bottom its most likely an FE (360-390). if they are left to right its not.

The shape of the flange can also be a clue. Rectangle is FE.

I had a 390 one time and priced headers for it, I quickly chose to swap it for something more reasonably priced to build.

Well The headers are the wrong application for my truck. They are FE headers but I believe that they're for a 390 GT engine with 14 bolt heads, not the 8 bolt c8ae-h heads that I have. Thanks for the help though.
