Something like this is another option http://www.permatex.com/products-2/product-categories/thread-compounds/thread-sealants/permatex-thread-sealant-with-ptfe-detail

The temperature rating is key as these are near exhaust gases. I use this for many coolant applications with great results and is non-hardening. Will also provide a barrier for corrosion between the steel and aluminum.

Don't use anything that would keep you from being able to remove the ball studs. I also use Permatex thread sealant which will work just fine for this application.

Locktite would be a bad idea.  Someone did that or something like it, to the ball stud over the 6 spark plug before I got the car and the threads in the aluminum head were destroyed when it was removed.  I had to drill it out and put in a thread insert.  Definitely use the permatex thread sealer.  Otherwise it WILL leak.
