lb7 head stud torque???
 
Just got my arp head studs @ was reading instructions on proper torque says to torque to 125lbs in 3 equal incriments 40,40,45? total 125-else where on this site it was posted to torque to 125lbs loosen torque to 125lbs3-4 times - what gives?

I would do the proper increments to 40ft-lbs, 80ft-lbs then 125ft-lbs in proper rotation around the head, then once you've torqued the last one up the remaining amount go around and make sure each one is at 125ft-lbs. As far as I know I thought this is just standard procedure :humm:

when i did mine it said to follow what they said to torque them down to.



i let them sit over night too after the second trq sequence and a few of them were a little loose.
