I'm reading the service Manuel and having a hard time coming to terms with torqueing valve cover bolts to 11ft-lbs/ 132 in-lbs.
I never thought those little bolts could take that and I don't want to strip out a bolt on the valve cover. Any input would be welcome.

I agree. I torque these (This size) to 80 inch pounds, initially. If there's any 'weeping" an additional 5 inch pounds. If weeping continues, I replace the gasket.

A long time ago... in a garage far far, away... back before I owned a an inch point wrench and believed tighter is always better... I over tightened the outside valve cover bolt and an outer section of the head cracked off. Ugly little scar from that point on, but lesson learned!

The Machinery's Handbook  may be a little much for the average Joe to have in his library, but it's in mine. Full of all kinds of information regarding machining practices, fits and tolerances. So in lieu of this , here's a snap shot from www.classicmotors.com of a torque chart for different metric fasteners.
