H6-3.0 and I kept both hot lines from the engine separate all the way to the radiator. Easier to bend the smaller lines, combined pipe cross section area a bit larger than the single FFR pipe. But you just want to see the routing in general, I know.

Like Bob-n-Cincy there is room for heater lines here too. I had them one time, but changed to a tap up front that just uses hot from the top of the radiator (longer to heat up but OK with me). Back at the engine I used the heater line to feed an EGR cooler, if someone is wondering...
