I use a torque wrench on the ones it can reach then tighten them just a tad more with a box-end wrench to get a feel for how much torque that is, then use the wrench on the hard-to-reach bolts. I'm pretty O-C (leave out the D because that's bad grammar!) so I tend to go over all the bolts in order once or twice again once they've been torqued just to be sure.
Not sure about everyone else but when I use composite intake gaskets I can feel when the gaskets stop compressing and that's when I know it's tight enough. Usually ends up being a few lb-ft more than spec but more often than not I use feel more than torque readings, or both. The way a bolt or nut snugs down can tell you a lot about how it's clamping up.
