Here is a suggested updated torque spec for this engine's rocker arm bolts;
Rocker arms
Step one: Torque to 11 ft lbs then tighten an additional 90 degrees of bolt head rotation. Some guys don't fuss with the torque specs and just get them good and tight. Either way, be careful, as the heads are aluminum. You do not want to over tighten these bolts

Rocker arm strip, loose, or breaking


I have had several rocker bolt holes strip on these, buying a helicoil kit seems to hold good but I prefer to install a steel insert, either kit with instructions is available at your local parts house what i have found is that the vehicle has usually had an intake reseal and the rockers are over or under torqued, but sometimes not..

There are some awesome adhesives on the market. I am thinking about one for boats and just remember "1500" as part of the name. With marine products you will not have any problems with moisture separating it so car washes will be okay.
