I have had a look back over previous posts but there seems to be a lot of opinions to what is right and wrong !!!!

I'm running a cometic h/gasket and arp stud and nut kit at 20psi boost, when fitted they were torqued to 80ftlb, head and block were skimed. Now at full load the cooling system pressurises and blows past the expansion cap, if drive at low boost it will drive all day long with no abnormal cooling system pressures...i've rechecked the head nuts once cold and they all didn't move when i rechecked the torque...

Would you slacken them one at a time and retorque checking the studs haven't moved (i've paint dotted the tops of the studs to see if they move) and if so what would you torque them to ??? I havent any lub that came with the stud kit !!!

Any experienced opinions please.....

Thanks Guys,

Sean.
