And a 6mm cork gasket needs to seal the oil tank?
I'd change the design, and buy a John Bickford book about gasketed joints, and some design guides as well as this sounds like a really bad idea.
just my 0.02$ worth...
RE: torque value
The level of help that you require is far beyond what you can reasonably expect to achieve for free in an internet tips forum.
You need to hire a qualified mechanical engineer.
RE: torque value
I think the OP'er should get some local engineering and design help with his problem, from his boss or a senior engineer, rather than coming here for a supposed simple formula, all rolled into one, to solve his problem. If for not other reason than to keep his company out of legal trouble, but more importantly so as not to hurt other unsuspecting people or electric rate payers who buy their equipment. This is not a particularly difficult design problem, but the OP'er doesn't even show the basic engineering understanding to break it down into its parts. As he describes it, it sounds like a bad design to me too.

6mm?
RE: torque value
It looks like for transformers above a certain size the lifting function is kept separate from the cover. I have no clue if that might even be driven by some code.

Anyhow, how much does this thing weigh? Can you give some dimensions? You'll want to do a proper analysis to make sure that something doesn't break and kill someone.
Usually you'll want to crank the bolts down to 75% yield or something along those lines.
As was said, asking a gasketed joint to do yeoman's work is probably not a good idea, unless you've specifically designed it to do so.
