The main thing about exhaust manifolds is to keep the velocity of the exhaust gas up high. That is why the spool on the stock manifold was better. It probably had cracks in it, so that could have cost some top end. The larger manifold runner probably was hurting more than anything on a 14b. For what it sounds like your stealth is going to be, I would stick with the stock manifolds.
