just some exhaust opinions? 71 k10

[dmartin1]

hey fellas,just seeing what your opinions are. heres the story.

71 k10 longbed. the body looks ok but is all reality CRAP(cab was in a wreck at sometime and bondo-held together with paint on top) bed is crap also.with an honest problly 2 gallons of bondo on it.
so i am swapping my 1-owner 67 never wrecked almost no rust body onto it(small cab window too )


the engine is the stock 1971 350. it is 100% stock from air filter to oil pan EXCEPT for the headers on it that leak badly.it has 78k original miles(owner kept a detailed log of everything since new in glovebox)

should i replace with new longtube headers or factory manifolds for a 71 k10?
this is going to be a daily kinda truck.real clean.
