don't.
just make sure your not re-using your old "torque-till-yeild" bolts. buy new ones.
and torque the new ones down to the proper spec.

I use ARP thread sealer that I got from Jegs. It's a 7 oz tube and it works great.

That will be ok for head bolts. However I have found that gas breaks that sealant down so I wouldnt use it to seal rocker studs or intake bolts....
