Default 351 vs 289 Dual Plane Firing Order

As the firing orders are different, will the Blue Thunder 289 Cobra Hi Rise dual plane manifold give maximum performance on a 302 block with a stroker crank that uses the 351 firing order? In theory dual plane runners are sequential so as each intake runner is 180 degrees apart in the firing order. I know it will fit, it's just getting maximum flow that concerns me.
