When it went, I drove the car 25 miles with that stud in my pocket to a friend's place to install a Helicoil and the head gasket was fine (still is).
In your case, if you are concerned, I suggest draining the coolant to below the head and go for your life.
BTW, Why are you opting to do things that way? There would be no drilling into the head if you were to put a short length of metal tube in the top radiator hose for your source of warm water and return it to the one running from the bottom of the radiator to the engine. A thermostat fitted above the attachment in the top hose would help the flow.

I am new to Model A's, but mine runs fine but does weep at a small spot on the left side between the cylinder head and block. I was going to replace the head gasket to fix this, but according to your comment this is normal? please explain further.
