The bolts can easily achieve the proper torque, trouble is, they never achieve the proper clamping force on the pan. The bolt bottoms, and torque wrench clicks, before the gasket is properly squeezed in there. But yeah, the crappy cork gasket really wasn't the best idea......

Yeah, I did the math on the plate movement, and it was in thousandths of an inch, so, no, that certainly isn't the problem. Its the BOLTS that are a hair bit too long, along with a crappy cork gasket. A good fel-pro gasket, new, shorter, bolts, would likely solve the problem as well. The hughes plate IS a good product, if you have the money, go that route, if you wanna go cheap, just to the gaskets and bolts. (or, simply but thin washers under the current bolts.)
