Head bolt sealer?

[dodgerunner]

Do the head bolts on the 3.4 PR engine go into the coolant jacket? I had put my head on already and read that the 2.8's need thread sealant. Is this true with a 94 3.4?
Thanks

Putting that stuff on the threads will effect your tq readings so be aware.

I am not sure if any of htem go into a water jacket or not. whenever I have pulled my headbolts out though they have all been dry. Maybe I am wrong though.
