Beam type wrenches work well for head bolts but when trying to torque a bolt in a tight place you can't get a view of the reading. To view the scale properly you need to view the scale from straight above it, not on an angle.
There are many videos and postings showing how to replace the head gasket on Intek engines. All of the ones I have watched show the head bolts assembled and torqued dry (no lube). Is this correct or should the bolts be lubricated?
