Thanks Bill,
What I recall from earlier discussions, pump flow to pressure is a
square law. To double the flow, I would need to increase the pressure
a factor of four. If that's the case then it seems that I would only
get about 6 * 1.4 ~= 8 1/2 GPM flow with the pumps in series. The
radiators would be connected differently but it seems unlikely that I
would get more than 12 GPM. I will have to try it. It's looking like
a single WP336 (55 GPM rating) might provide better flow.

Bob,
Good to have some data. I have attached a crude sketch of how pumps (centrifugal) act when in Series or Parallel configuration. When is series, the pressures at any given flowrate add, when is parallel, the flows at any given pressure add.
The added factor to be considered is the load curve that you are working against. Where the load curve crosses the pump curve(s) is where the flow will stabilize.
It looks like your pumps are on the low side of pressure generation given the restrictions that you are asking them to pump through.
