I'd like to remove the factory (under the dash) heater from my 1967 MM 1000.
I don't use the heater in Arizona and it takes up a lot of room under the dash, above the parcel shelf.
I plan on adding a instrument gauge cluster (oil pressure, water temp and tachometer) under the dash
where the heater controls and box are currently located.
I see the two brackets on the back (firewall) side and the two screws mounting the heater to the underside of the dash panel.
Here's my question: If I disconnect the heater inlet hot water hose from the control valve on the cylinder head should I close the water circulation loop by reconnecting the outlet hose that is connected to the black metal pipe that comes from the radiator hose. I understand that closing the control value will stop the water flow into the heater. But what should I do with the hose that is connected to the metal pipe that comes from the radiator hose once I remove the heater?
Could you please reply and thanks very much!

Closing the valve will reduce the flow, but is unlikely to seal completely. It is possible to remove the valve, fit a blanking plate, and replace the radiator bottom hose with one that does not have the return pipe fitted. However, there is a strong argument that blanking off the heater will lead to hot spots in the head. I recommend that you do join a short loop of hose from the heater tap to the return pipe. You will also need to blank off the air intake - remove the large diameter hose and fit a plate over the hole in the bulkhead (firewall).

Thanks for the information on my question and your quick reply!

As above, make a loop - but you may want to retain the fresh air inlet! I would... Instruments down there will be hard to see - they should be easily in your field of vision as you drive - without taking your eyes off the road......
