Could somone describe for me please, the stock set-up for a '66 F85 with the 330?

Our car has (had) what appeared to be an aftermarket cooant heater plumbed into the system. It used a T fitting, which we broke as we were getting the new hoses on. We will probaby just not worry about the coolant heater thingy, since we do fine without them on my other cars.

Here is what we have:

A short 5/8" hose from one heater core fitting to the back of the intake manifold.

A long 3/4" hose from the other heater core fitting to the water pump. This is interrupted in the middle of that run with the T fitting which we broke.

The T ran down to the coolant heater (which was mounted near the frame), and then over to a fitting on the drivers side of the engine block. I am assuming this fitting and the run over through the coolant heater and up to the T is not a stock set-up, and am thinking if so, I can just cap the block fitting off somehow?
