New heads going on, what to torque them to? I am getting ready to get the new 6.0s on the new block and was wondering what would you pro's i.e. Harlan, Stealth, LS1/QMP recommend I torque them down to?
Specifics on my set up,
6.0 Alum heads
ARP Head Studs (Standard issue)
GM 6.0 MLS headgaskets
No O ring/reciever grooves in heads
Boost Level that the motor will see 15psi.
Thanks,
J

Re: New heads going on, what to torque them to? I had/have about the same setup for studs, gaskets and heads, no grooves.
Studs in hand tight with lube.
Torqued to 70 ft-lb with ARP/moly lube on the big studs, 22 ft-lb on the little ones(same as stock bolts).
So far so good, but we'll see in another week and a half if that still holds true. But that configuration was sufficient for 15 to 18 psi

Re: New heads going on, what to torque them to? Thanks Harlan, That's just what I needed to know. So you will be running those same torque specs on that twin turbo beast? 
You DA MAN.
Stealth, did you run the car this weekend up in colorado?
Thanks,
