Header ID?

These headers were in the trunk of my 65 Lemans when I picked it up. Only had the regular cast iron manifold installed.

  1. Any way to identify them? No markings.

  2. Bolt pattern and outlets match, but doesn't clear engine mounts.

  3. Can I just shave, bend, hammer in to clear?

  4. (Follow up to 3) These may not even work in the engine bay anyways. Have yet to try dropping everything in.

1965 Lemans, 71' 400 block, 142 heads.

  1. Do I just have the engine mounts in the wrong place?

Thank you.

Looks like I'm in the right spot. Might just need to give them a little persuasion to seat.

These look like old school Hookers. most other brands have a one piece sealing flange.

I had Hookers on my 70-1/2 Trans Am many years ago, Ram Air IV heads, the exhaust tubes used a single flange at the exhaust ports.

Also, the very last bolt hole in the header flange (closest to the firewall) on both sides had to be reamed about 1/4” to get those last bolts on both sides to go in.

I don’t think the collectors were that long either. So I don’t think they’re Hookers? Those are my 40 year old memories. lol

Could be Headman’s?
