figuring out how to plumb my heater. planning on having PS front manifold bung supply hot fluid ->valve->heater intake->heater output->water pump barbed fitting.
should I run it over the intake manifold or around the side?
what to do with the other barbed port on the water pump? i've seen some attach it to the bypass on the water neck. if i did this, would i need a T radiator cap with an overflow to go to my overflow canister? should I cap off the extra barbed fitting on the pump and connect my waterneck bypass to the overflow canister?
thanks in advance.

Mine was a very different custom approach, using the mall heater assembly from Southern Rods, mounted on Pass side, and built a custom plenum/box to force the air up to de-fog vents, and two simple openings above the tunnel for feet/leg warmth. Heater hose routing was off to the side, out of sight and out of the way.

Notes:

OLD engine pics! Since the picture, two more motors, but heater hose routing the same
Scavenged heater parts from the donor
Hi or low air chosen by open or closed position of ball vents on top of dash area
