Elderbrock air gap intake question

Watchthis said
A small block mopar doesn't have water running through the rear of the intake. At least that's what I always thought. The head gaskets are designed to block th rear passage and force it to cross in the front, where the T Stat is. AM I wrong in this?

Partialy wrong. The intake is so designed to force the water from rear to front, not the gasket.
but you have the idea.

Just a pure SWAG: Since the standard water flow direction in the heads is back-to-front, it would not seem intuitive that it would do so; I would think it would only change the balance of flow between the heads. If one head's combustion chambers got a bit hotter and raised the local pressure in that head, it might even divert more flow to the cooler head....

Please define "SWAG" for me.
The way heat works is, it goes where it isn't.
The best way to cool a set of small block heads down is to take water form the center out of the head. (Because there are 2 exhaust ports next to each other. Hence, a hotter area.) While not allways possible, the next best is to take it from the rear of the head.
This system seems to work very well for the racers and there high powered engines.

I would add to the question: does adding the rear port by-pass (so from one side to the other) improve the water flow in the SB Mopar engine?

No, one side to the other is not how it is done. You would tap both sides of the intake and run the water hoses to the front of the engine in a modified thermostat housing.

here is an example of a thermostat adapter that can hold 4 extra water hoses. That would be left and right side heads, middle and rear of each head.

Here is a simple front to rear water neck adapter and it is plumbed for you to see.
