best way to seal a stud from water jacket

[1930artdeco]

Hi All,

Update time. I lapped and gapped my new valves and am soaking the block in evaporust now. I checked all of the stud holes just on a whim and found that the one between the #2 valves went all of the way through to the water jacket. What is the best way of sealing it off from water? I could use JB weld but then the stud will be glued in permanently. I was just planning to use a lot of anti-seize and match its height and threads to the rest of the studs around it.
