Radiator water, in significant quantity, is being forced out the over flow line in my 1936 V-8, even when engine is running cool and more water than just thermal expansion. So, I guess I have a blown head gasket, with exhaust gas leaking into cooling water circuit (although, I realize it could it could be a crack in cylinder wall instead). Presuming this is the case, is there any simple way to tell whether it is coming from the left or right cylinder bank?

You can remove the water pump belt, start the engine and look for bubbles in the radiator filler neck. If you find some, drain the coolant down a bit and remove the upper radiator hoses. Fill the heads until the water is even with the top of the head outlets, and start the engine again. If you have a leaking head gasket, that side should show bubbles. The Ford V8 is actually two four cylinder engines on the same crank and cam, with the coolant merged at the radiator. This allows individual diagnosis of the sides. If you do have a leaking gasket, check to see if there is water in the oil. In that case, don't run the vehicle until it is repaired.

Another suggestion is to check the spark plugs which might show which cylinder is leaking . Just another idea.
