2 sets of BB valve covers, WIW and is my ID correct?

i have two sets of steel big block valve covers that i am going to be selling for my dad. cant remember what they are off of though, also wondering what they are worth.

i believe the orange set came off a 70 440+6 car?

and the blue ones off a 383 dart?

im not 100% sure. i used the valve cover id thing off tonysparts page, and based off what his pics say it matches up to cars that hes had.
