What torque for head studs and cometics

[turbowrenchhead]

Got a set of .078 thick cometics. I want to lower my cr and this is a easy way to do it. I hear alot of different head torques that guys are using. I have apr studs and the lube. What should I torque them too?

With 0.060" thick cometic with 30W oil on ARP studs with iron heads I use 85 ft#. HTH

ive read that changing the squish volume of the chamber by way of changing the thickness of the headgasket is a bad way to do it and my result in more detonation. might want to check with some experts about this.

I talked to Dan as DLS performance and he said the anything over 75 ft pds the stud will stretch and therefore loseing tension. So he said 70 across the board. I took his advice and I cold retorqued them 4 times.
