Thanks for looking in and more pics tomorrow.
Running rads in series is usually the best way to go. You can run rads in parallel, but in order to do so, they need to be the same type and size, and have the inlet and outlet tubing running evenly to them. It is a lot harder to mess up rads run in serial, and the performance difference between serial and parallel is negligible. This topic has come up a number of times before, and I'd have to do some digging to be more specific.
