well i dont think you have any other options... i would just do it and hope for the best... except for the missing one. maybe you can order just one?
I have arp studs in my TDI I torque them to 105 ft-lbs.With the metal head gasket you gan actually feel it stop compressing at approx 100 ft-lbs.I just go to 105 to seal the deal :lol:.Any less than 100 and you are asking for possible leakage.
