Used them in my brothers rally car no problems...used Threebond as well (make sure to use a VERY thin coating)...o-ringing is a must and the block and head must be machined perfectly flat (machined!). If any of these requirements aren't met, chances are the seal won't last. Generally copper head gaskets aren't too problematic, if they are chances are something was done incorrectly.
