I'm pretty sure that some head bolt holes in SBCs go into water jackets. New head bolts come with a sealant on them to prevent them from leaking.
That sort of fix in a can may stop a leak, but it also clogs radiators and heater cores, and whatever other small passages exist in the cooling system.
We have water appearing out of both head studs at #1 cylinder.
Motor Head partner says it’s not abnormal and put a can of stop leak in the radiator, and don’t worry.
I worry. That sounds a bit like.... “ Crap I screwed up... hope this works” ... to me?
Haven't looked under the Valve covers yet....... need the cocktail hour to bolster.
Any experience with this?
Thanks

Are you talking about the head bolts under near the header flanges? You might want to try a can of sealer (I use Irontite) to stop the seepage. There is no harm in it. If it doesn't work, you're ready for a teardown.

Their studs not bolts... small difference I guess.
Our Motor Head is an ARP freak.
Steel heads. Brand new build. maybe 20 miles on it....
Not fond of the idea of Stop Leak in a brand new everything
Any opinions on pulling one at a time sealing and re-install??
Not a big deal. You could drain the coolant, remove the offending stud, and then apply sealer to the threads before reinstalling. If you have several that are leaking, only R&R one at a time in order to prevent the head gasket from walking.
Btw...do you mean aluminum heads? There are iron heads and aluminum heads...no steel heads.

Sloppy Semantics ... they are iron we have taken to incorrectly saying steel or aluminum.

But, I'd try to seal the individual bolt/studs IF they will come out, and if they will NOT....bolt it up and drive it..
DO NOT listen to your "Buddy" that has ZERO $$$$ invested in THIS engine when he tells you to put TRASH like stop leak in YOUR new build.
Thats asinine. Thats bubba mechanics at its finest.
ANY type of stop leak will block steam vents, water passages in heads where gaskets overhang the stop leaks will finish the job and cause that area to FRY with no fresh water flowing.
A wet spot around studs is normal. They are supposed to be sealed before assembly...but obviously someone didn't read that page. Chances are that they will corrode or seal off with what little trash is in the system.
Go ahead and run it and don;t worry unless the oil gets foamy OR you start loosing coolant. Check dipstick everyday for awhile and pcv for foaming. if none, forget about it.
Most engine machine shops have have sealant tablets they put in the block for coolant leaks.They are the same tablets that GM has used for years in their new motors.I believe they are made out of crushed walnut shells.I have seen them stop some pretty good leaks at my friends engine machine shop.They will not clog anything up like stop leak.I would drain the coolant pull the leaking studs and reseal as suggested.I've seen this done at my friends machine shop.It's not uncommon when using studs to have a leak.
Remove the studs, smear some sealer on the threads and reinstall. If you did not use any sealer, do them all now. Ive been using RTV for this since it came out with no problems.
