You didn't mention which gaskets you're using, but most of them don't require a re-torque anyway... [/B][/QUOTE]
I agree with Quickwrench. If you bring the bolts to their final torque spec then back each one off 30-45 degrees and retorque three times before moving on to the next one (in sequence of course), i.e., mate the threads, you'll be okay. Indexing showed an average of 22* increased rotation on each bolt due to thread mating (more than if 100# of initial torque were applied). I don't believe the ARPs stretch much, i.e., l believe "lifting" is caused more by lack of thread mating than by bolt stretch. Drain the block prior to installation, tap clean each bolt hole, torque bolts prior to adding water, install the intake with an old gasket and torque to around 20# after initial torque of around 10# on both heads (to assure proper alignment), increase torque only 10# each increment and do both sides simultaneously, let sit overnight, backoff/retorque in sequence, then FORGET about them. In fact, backing off and retorquing after heat cycles will result in LESS bolt stretch/rotation, inferior thread mating and possibly inferior thread seal. This can be proven by indexing the bolt heads (marking a straight line across them and on the head to visualize change in rotation) prior to the retorque. Good luck, Joel
