Gary,
Regarding retorqueing the head:
1. Did you use anti-seize on the nuts upon the initial mounting?
2. Do you back off the nuts some before the retorque? If so, how much?
3. Do you do the retorque on a cold engine, or run it up hot first?
4. Do you do another retorque at 1000 miles?
Thanks,
Pete Pollock
