Thought I would pass this on to everyone. Where I work we use a Dow Corning product called "MolyKote" G-N Metal Assembly Spray
This product could be the answer to exhaust manifold bolts, and or manifold bolts that gall up or just hard to turn out. We use it under high torque and high temperature (500+ degrees) conditions.
Properties:
Excellent protection against fretting wear and corrosion
Extends service life
Low friction
Lubricate beyond the yield point of most metals in boundary applications, reducing wear and helping to prevent seizing, galling and excessive friction
Aid run-in and reduce frictional force and surface damage
Low coefficient of friction allows for effective conversion of
torquing force into holding force; reduces the force required for
disassembly of threaded fasteners
COMPOSITION
Solid lubricants in mineral oil (with non-chlorofluorohydrocarbon
propellant in aerosol

Bruce and all other interested parties:
Be aware that MoS2 does not break its film strength with any normal load. So, if you use it on the threads of fasteners tensioned by torque alone, there is a very high probability of failing the fastener in tension before the specified torque is reached.
Is this a problem? NO
Just don't use a torque wrench, use your brain instead. When the assembly feels "made up", quit right there.
