Does anyone know what the plenum to intake-manifold bolts should be torqued to? I can't seem to find it... I wanted to check that they were tight and tried applying 10ft-pounds of torque and the head came off! :damnit:

nope handy dandy thing called a computer with a conversion tool.
Figured not everyone has a torque wrench that reads in INLBS.

Thanks. I'm surprised that it broke by applying 10 ft-lbs if it's supposed to have 5.9-8.8ft-lbs. Unfortunately my torque wrench only goes down to 10ft-lbs. Maybe I should do the suggested 1/4 turn trick.

This might be a dumb question, but why does it only list "Upper Plenum-to-Intake Manifold" for the DOHC? Mine is a SOHC.
