There is a pretty good how-to on the engine rebuild. Although they use head bolts in the how-to, not head studs.
But I'm sure the manufacturer of your brand head studs would have installation instructions for them.

When I purchased my ARP head studs they did come with instructions and grease. Grease for the threads, go hand tight with the studs. And the nuts get torqued in 3 steps ending with 85 ft lbs. There is a specific sequence they need to be torqued in as well. If you are re-using them I can post a link with information I have about them.
