Default 88 Runner Torque

Anybody know the torque specs for the intake runners? I can't find it in my FSM. Also, should I use locktight on the runner bolts?

Thanks

I can't remember the source, but I read somewhere that it is 20 lbs.
I would not use locktight on these bolts.

25 lb/ft torque. No thread locker. If anything, use anti seize. In your FSM the info is under intake manifold install, at least it should be.

25 ft lbs is correct , below is from a automotive site. And yes use antiseize on the bolts...WW


.Install the runners, gaskets and the runner-to-manifold bolts and tighten to 25 ft. lbs. (34 Nm).
