i was burning up gaskets left and right with the T3.0 in my RS4 for some reason (bolts werent coming loose, and both the exhaust port face and header flange both true'd). I just stopped using them. I use Loctite 518 anaerobic gasket maker now and have yet to have a problem again. Car now has a OS 18CVR in it, and still using the Loctite 518 with no problems.
Stuff works awesome. I also use it for sealing the engines
Only downfall is you cant get it at local autoparts stores...it must be ordered, and its not the cheapest stuff out there...but stuff that works good usually isnt
