interesting theory about the engine mount, and it does make sense in theory. you would need to confirm your assumption about the magnitude of the torque forces as well as whether there is truly an impact force imparted through a dead mount. also remember that as the engine twists, it is simultaneously pulling up on the other side mount. i have seen cars without the two bolts on the passenger mount where it meets the head, and have driven a saab for a while with a bad passenger side hydraulic mount without even knowing it - no symptoms, no noise, etc.
i am unsure of exactly where you describe the "back" of the headgasket but if you mean at the timing chain cover by the firewall then i would have to say a contributing factor may be that the gasket is quite narrow there - it is about a 1/4 or 3/8 inch wide only, and the metal between it is aluminum on both sides, whereas the gasket sits between aluminum and iron everywhere else. so you got different expansions vs. the rest of the head/engine, plus a transition from block to timing cover, plus narrower gasket material, plus maybe the chain doing a lot of vibrating, not to mention that the guide is attached to the chain cover.
i wonder if there is some chemical you could use on the gasket at the timing cover to make a better, tougher seal.
