mark them then turn them 90* for the final torque is what I ment. yep, the bolts can only strech so much before they need replaced

so pull them out and look how could u tell if they need replaced

basically if some don't tighten like others do than the prob stretched. if you are gonna re torque your head make sure you oil the threads of the bolts before you reinstall and torque them.

alright your the man!
