That's how my HJ was originally plumbed. It worked fine that way, I just thought I would get a better coolant flow hooking it up the way I described.thanks again chop. will it still work well enough to just run both to the thermostat housing??

cheers chop
cheers for the pic evilsim would mind mine looking like that..

LCs come out from the thermostate and waterpump on the drivers side and cross over the top of the rocker cover.
LJs come out of the passenger side of the theremostate.

The thermostat housing has two outlets one inlet(apart from the radiator hose) Two +ve outlets horizontally opposed at the top and a return/inlet at the bottom. The other inlet of course is at the water pump. Either set can be used.
In answer to the question, which hose to connect?, either way around will work, but for what its worth(youd need very cold air and an incredible blower to cause restriction of flow due to convection), work with gravity not against it and connect the outlet house of the motor to the higher connection on the heater

dont forget as pictured above the thermostate bypass.

The laws of physics dictate that it will work. And as I previously posted it worked in my HJ, so I can state it works in practice as well as theory. If you want a scientific explanation, I can provide it. Without doubt, devils could as well.I can not see how it would work if both hoses are connected to the thermostat housing.

I would be happy for someone to explain to me how water will flow through the heater core when both hoses are connected to the thermostat housing.The laws of physics dictate that it will work. And as I previously posted it worked in my HJ, so I can state it works in practice as well as theory. If you want a scientific explanation, I can provide it. Without doubt, devils could as well.I can not see how it would work if both hoses are connected to the thermostat housing.
Just to make sure that we are all talking about the same thing lets take the photo above and assume that we block to two pipes on the water pump and connect the heater hoses to the two pipes on the thermostat housing.
The first problem I see with this is that you have now blocked the thermostat bypass circuit which is not a good idea as it is important to keep water circulating even before the engine has reached operating temperature to avoid uneven heating of the engine. The second problem is that both hoses share the same hole so the pressure would be the same and there is no reason for the water to go though the heater core.
I can see that the water will eventually get heated by heat transfer but I can not see why it would flow or that the heater would work effectively.

The red six, as I thought perhaps we were talking about in the TA-LJ sections, is not the same:
Perhaps that isnt clear, there are three connections to the thermostat housing, 2 +ve, one -ve(this is separate to the +ve ones and returns the flow to near the water pump.The thermostat housing has two outlets one inlet(apart from the radiator hose) Two +ve outlets horizontally opposed at the top and a return/inlet at the bottom. The other inlet of course is at the water pump.
Does that clear it up?

Hot source from thermostat outlet,
Through heater core,
Return to waterpump inlet side.

I did not see your post @ 9:42 which clearly stated you were talking about six cylinder upper and lower thermostat housings.
I should have known that we were talking about a 6 cylinder as the first post asked about the top and bottom thermostat housing connections.

This is a photo out of one of my 70s magazines
Be extremely careful when taking off or putting on of the hoses of the heater core.
If putting on make sure you support the pipe coming out of the heater core.
When taking off MAKE sure you undo the clamp fully then slit the hose that is covering the heater pipe with a sharp knife .
If you fail to do any of these then you WILL run the risk of breaking the pipe away from the heater core as that is a very weak point.
Unfortunately with the LJ I had, I had "been there, done that"
