Header I.D help

[chevyman0429]

I just picked up these headers in some trading but not sure what they are and what they fit! The guy I got them from said the guy he got them from said they were appliance headers for a small block ford and early mustang body ? They do have the square collectors on them! Any help would be awesome as I need to list them for sale! Thanks

Stamped on one pipe on each header is 5602 down close to the bottom ! Does anyone know this part number or maybe have an Appliance catalog? Thanks
