Leaking coolant (1946 239)

Hi
It's finally done! My engine is back in service!
After being rebuild i've reassemble everything and start it!
It start on second attempt! It ran for 30 sec and I stop everything to make sure everything was ok.
The only problem is that one of the head bolt is leaking a little bit of coolant.
Only small drips...
I'll check back the torque on each bolt tomorrow.
But do you think this is normal?
Any advice or trick?

Thanks!

Did you use a sealant on the studs? Pretty common issue with the 59-series engines. It may just stop on its own.

Ross, I think I have asked you this before but what sealant do you recommend on the bolt threads?

On my 8BA (which uses bolts, not studs) I use anti-seize. The guys with stud engines usually recommend either Permatex #2 (non-hardening) or GM Part number 012346004, Teflon® Pipe Sealant. 50 cc's cost $18!! But its supposed to be the best.
