Spec is somewhere around 10 in-lbs I believe, but with these bolts, I'd say tight is tight, and too tight is broke.
A simple google image search will yield the proper sequence for the head/intake manifold bolts. But it is almost always the case that you start with the bolts closest to the center and work your way to the front and rear equally in sequence. Ideally you will use new head bolts, as your factory ones are torque to yield (if I remember correctly).
