You can use any of the following Loctite products:

Loctite 518
Loctite 51813
Loctite 51818

Apply to the threads, let it dry and re-assemble..

We always used the GM brown sealer in the can with the applicator attached to the cap....

It looked like Permatex Aviation Form-A-Gasket only thicker.....

Nasty stuff but it worked great on studs and bolts..........

PS:
Don't forget to add a good block sealer such as Moroso Ceramic Block Sealer or K & W Metallic Block Sealer

Richie,
Always found that on studs it helps to actually put some of the sealer in the threaded hole first. Not sure why it works, never do it with bolts ? If you are fixing it without pulling the head, pull the stud completely out, get some sealer down in the hole with a screwdriver or something and then thread the stud back in.
