Bob,
I’ve tested both ways. For my setup, parallel works a little better. With a basic in/out manifold and equal size hoses the temperature stay within 3 degrees of each other. Probably airflow.

While the subject is on cooling, my question is for those that are using 2 radiators. Are you plumbing the radiators in series or in parallel, and if in parallel what are you using if anything to give a good hydraulic split on the coolant flow?
Jeff,
I think common. I got it at a local auto parts store.
