Heat Riser for 250 ci. Straight Six

The heat riser on the exhaust manifold on my 1972 250ci straight six is shot. The counter balance is hanging and the spring is shot. I have two questions, is it even necessary, I run a manual choke, or can I just wire it to the manifold in the open position? Secondly, what is the open position? I take it it is when the counter balance weight is hanging down? I would rather not take the exhaust manifold off to find out.
