Wow, talk about going in reverse......
You have a unicorn, I bet nobody has ever done this swap before so I give you a couple options, look for engine swap headers for your year body with a push rod 5.0, I doubt there are any, so likely will have to custom build them, good luck.
If you're into fabrication you could possibly build them yourself.
