If using the hemi pistons (which I advise, due to compression loss), the crank balance will be off, I don't know how much. You don't need an intake manifold - the poly will fit (any 1956-58 315/325: 2 bbl., 4 bbl., dual 4 bbl.). Exhaust manifolds are different bolt pattern. Heads complete with all 4 rocker shafts and all parts incluing pushrods. Lifters look the same.
