The Vortecs flow better because they have better runner designs, have a much more efficient combustion chamber design, and can be purchased brand new for the cost of overhauling an old set of 441 heads and doing some bowl blending on them. IMO, the only real advantage to using 441 heads would be to a restorer who wants an original matching numbers engine.
