Retorqueing a U20

["John F Sandhoff" <sandhoff@csus.edu>]

I'm helping a friend with the infamous U20 head gasket oil leak.
I know the cure will be pulling the head, but in the past there's
been discussion about trying a retorque first. Anybody have positive
experience (and a preferred methodology) with successfully retorqueing
the head to cure the leak?

I can hope, can't I?
