heater core water flow

[RootBreaker]

Ok so now i got a delema...
every 2 years i have to replace a rubber plug on my radiator...
it just rots away.. guessing from the antifreeze...

so currently i put a 1991 motor in my truck... so hose from water pump to heater core.. then out of heater core to intake.....

well i cant just plug the radiator and dont want to deal with it anymore..

can i just plug the water pump (in the back as i know you can unscrew the nipple and put a plug)... and run it to the radiator?

just want to make sure i get the flow right....

that's the way mine, mothers and several other trucks i have seen are run, rear of intake is a water outlet going to the heater core, coming out of heater core back to radiator.

yeah i was thinking you would get better flow off of the water pump....
so will plug up the water pump and go radiator and intake... to which mine is in the front of the intake...
