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.
