8BA head studs leaking

I would use non hardening Permatex.
Use it on the threads.
And into the block ahead of the studs/bolts.
Use a pencil or something to get it below the top of the threads.
Do one bolt at a time if you're already torqed up.

I had that happen once when I flipped a gasket over by mistake. Starting over with a fresh head gasket solved the weeping around the bolts.
 
I like Karl Wolf's suggestion of removing on bolt at a time. Are there any bolts that go into a water jacket. That would mean draining the coolant. Is that correct?
Cheers, Byron.

most of the bolts go into water jacket. you would have to drain some coolant and i would want bolts and thier holes clean abd dry before using any sealant. Mark
 
I do 2 or 3 at a time until I've got all 24 on a side done. Make sure you drain the coolant out and that the threads are dry or else it wont seal properly. Use a liberal amount of Permatex #2 and wipe away the excess then let them dry at least 24 hours.

Just about every studded build here gets Permatex #1 (hard-setting), Chevy's OR Flatheads.

Have never experienced any stud leaks using this sealer, and we've dynoed hundreds upon hundreds of units!

Thanks, Gary in N.Y.

P.S. Having said that above here I would add this, do not install any anti-freeze until you've established there are no leaks with plain water. The anti-freeze will impede sealing any small leaks if they should occur? Be wary of the ambient temps though, you don't want any freeze-ups.
