I've deleted the coolant line that runs through the intake manifolds on my 240. Now I'm UN- bypassing my heater core for defrost function to work properly. 

The "T" that connects the hoses under the spark plugs that feeds those two components, heater core and intakes outflow to the radiator will now only flow coolant from the heater core's outlet. Would this cause any problems?  Should I run a straight hose from the outlet of the heater core to the radiator's outlet to the water pump?  Confusing to me so any opinion right or wrong could help me to figure this out.

Thanks for any help!

site, i ran the hose from the head to the heater core, and then from the heater core straight back to the fitting at the water pump. no problems so far.

 

Thank you SwettyBetty, I'm gonna try the OE setup first then go for other ways like your's and Captain Fantastic's as options.

I think my core is good and okay but I do like the idea of the valve in the bay. So if all else farts out that's what I'll do.

Thanks again for your help. Cliff
