Does anybody know these Headers? Im trying to sell them but i dont know for what car. No Branding or parts number. They where laying in my shelf for years. I always thought they came from my dads 71 Challenger which had a 440 but looking up 440 headers on the internet the tubes are bent way earlier

 

Looks kind of like the old Hooker Pro Comp Dragster Headers for a dragster or a roadster.... Looks like a 440 head flange... but not 100% sure...
