Exhaust manifold bolts Q??

Dear God. I'm no expert but I'd never use Loctite on anything in the exhaust system. Exhaust system fasteners are enough of a problem naked.
The RAVE is silent, which means don't use nuthin, but I note that anti-seize is specified for the O2s so why not for the manifold bolts?
A year ago, six years after my headgasket job (I don't recall using anti-seize at the time) I found that the exhaust manifold bolts on the RHS needed to be re-torqued but I'd much rather build that into my regular routine than to not be able to remove a bolt.

I've used anti-seize most of my life, 40 years of being a mechanic, and never remember a manifold coming loose on account of it. No need to go crazy with the stuff, just a small dab on the threads...and tighten/torque to desired amount. On aluminum engines, I use the silver anti-seize. And use the copper stuff on metal/steel parts.
I'd never, ever use loctite on an exhaust bolt...and have never seen it recommended...especially on an aluminum head.
