When installing the cam towers do not follow the torque that is given by GM (10 ft or 120 inch pounds plus 90 degrees ) with out replacing the cam bolts
This torque is for new strech bolts ONLY !
Any time a torque calls for a degrees past the torque it is a STRECH Bolt !!
Some people have hand tighen or stopped at 10 ft. lb. and been lucky.
