A few points that may explain why I've never had any trouble with coolant
leaks at the head gasket:
1) The coolant is under far less pressure (and temperature) than the
combustion chamber.
2) The wire size (which BTW was 26 AWG, not 20) is only a few thousandths
thicker than the folded copper layer that it is next to.
3) The composite head gasket compresses quite a bit when installed. Just
the measured difference between new and used is around .010-.015", but I
believe it compresses further when clamped (and springs back when removed).
Those fine thread studs and 100 ft-lb's of torque provide a LOT of clamping
force.
