Porper head stud torque?

[BWatson]

So I'm putting a new head on my 12v and am using ARP studs versus the stock head-bolts. The directions I was told (including what is in APR's directions) say to hand-snug the studs into the block and only torque the nut onto the stud. Can someone explain to me why you would not torque the stud into the block as well as the nut on the stud? Isn't this the whole purpose of using a stud over a bolt? I always thought that you use a stud to equalize stresses. You torque the stud down in one direction and when you torque the nut down, in puts stress in the opposite direction and this equalizes the stress through the stud.

How does hand-snugging the stud into the block and only torqueing the nut, make this any better than a glorified bolt?

What have you done with your studs? Hand-snug or torque the stud into the block? I only want to do this once. This is for a ported, o-ringed head, that I plan on throwing some serious pressure into in the future and don't want to be blowing head-gaskets because the studs weren't torqued properly.

Thanks much!
