Big block exhaust stud sealant/locktite ? - 06/27/10 05:15 PM

Whats the best sealant to use on exhaust studs in a BB head? I don't want them to leak, and also don't want them to back out next time I have to fool with the exhaust manifold. It's in a motorhome,and will probably crack this one sometime in the future, like it did the last one. I plan on using anti seize on the threads on the manifold end of the studs. Any tips and ideas appreciated.

I prefer the liqiud teflon thread sealant goop. The incredibly messy white stuff that comes in the white tube. It WON'T leak. As far as making sure they don't back out I just cinch them in tight.

I was planning on tightning the dog dooky out of them Now I just need to find an Ethiopian kid with little skinny hands and two elbows on one arm to be able to reach in there and do it!

Double nut them to bottom out the shoulder into the cylinder head. High temp silicone for extra insurance.
