No, the current setup is fine with the hoses going to the bottom of the manifolds. For weak/low flow always start at the impeller
 
That's usually a sign that the riser's water outlet (where water and exhaust finally meet) is plugged. The hot side riser needs to be removed and rodded out with a coat hanger stuck in a drill. Stick a water hose in there and make sure it's flowing nicely.
