i need to know what i am supposed to torque these bolts down to. they are the double sided bolts that go into the head and are used to hold the valve cover down. i know that the nuts on top are 8ft/lbs, but i need to know what to torque the one that goes into the head down to. thanks in advance.

 

should i use loctite when putting them in or no?

 

16 lb-ft, and no don't use loctite
