Holley has a little vid on it -- but you don't hear it discussed all that much. Here:
https://www.youtube.com/watch?v=b8ROjrGAH2I In the vid they say you can only access the screw with the carb off the engine, but it is my experience that, with most of our manifolds, you
can use a right angle, short end straight blade screwdriver and make the adjustment on the car. With a non-removable Turkey Pan, it might be touch and go on that.
For a large displacement, decent duration camshaft, engine like most of the FEs that are in our Cobras, idling the 4160 off the secondaries is the single best trick I know, next to cleaning the air bleeds, to make the engine idle and run beautifully at low throttle.
