I have used the drill small holes in the thermostat method as well to aid in releasing of trapped air bubbles.

Shelby American's air bleed method was manual. Cars through CSX2200 used one of these "upper bleeder" tube assemblies near the radiator inlet with a Smiths® mechanical temperature sensor and a pipe plug. Any Cobra with factory installed 4-2V induction got one of these (early) or one set up for some other sensor. Street car parts through CSX2200 were normally just painted with black enamel. Later race car parts were often cadmium plated. I had the ones I made for restorations cadmium plated.
This is one of the Shelby American production drawings views.
I believe John Bessey makes nice recreations of these also.
CSX2201 and later street cars did not get "upper bleeder" tubes. Getting the air out after a total coolant refill can be a challenge.
