Hooker or Clifford for the /6 225???

Headers:
the cliffords are 16 gauge tubes 1 1/2" o.d and 2 1/2" collector
and the hookers are 18 gauge 1 5/8" and 2 1/2" collector
dont know if that makes a difference or not
clifford was 359.00 and hookers 469.95
Or..... should i keep the stocks :/
dont know if the price is worth the performance difference
i just bought a offy intake and a edlebrock 500cfm 4bbl avs carb to upgrade from the small single bbl holly
also thinking of getting 2 flowmaster 40 series mufflers and possibly a cam i dont know yet :/

The story behind this is:
My grandfather had a 70 duster 340 with the floor shifter a long time ago. i lost him 2 years ago to cancer but i asked him what was his favorite car he ever owned before he passed and he told me about his duster so im trying to clone the look of his in commemoration for him. so its going to be more body work than motor its just a crusier car for me but i dont want it to be a granny lol
