Mopar 318 heads

If I run what I have will I be able to use the brand new intake manifold I buy for my 318 on a 5.9 magnum? I'm looking at the weiand action plus intake with a edlebrock 1406 carb and a set of headers and hei ignition mod, and swapping out the 7 1/4 rear with a Ford 8.8 with 3.73 gears out of an exploder.
