Say what now? I am about to pull the trigger on a 2002 H6 ,,,
The H6 has a head-gasket problem at a rate equal or less than any car that has no unusual rate of failure, I think. No matter how good the gasket or the surfaces or the clamping, some small number will have a problem.
I would check the oil (and under the oil cap) for signs of moisture, and look under the heads for a greenish tint on the visible edges of the gasket.
If no signs, I'd call it good.
