[Fot] Re-torquing a cylinder head - GT6

[Scott Janzen]

I’m adjusting valves after the last race weekend.  For whatever reason, I put the torque wrench on a couple of the head bolts - and found maybe 90 degrees of movement on the few nuts I checked.  

I run a Payen head gasket - composite with a metal ring at the combustion chamber.

Should I:
loosen one nut at a time, lube with moly as provided by ARP, and retorque to ARP spec;
tighten from the current position to ARP spec (75 ft-lb)
do nothing

The engine has probably four race weekends on it.  I can honestly say I have never re-torqued Payen gaskets before, but I have also re-checked the torque on other gaskets and not found any movement.
