Need Quick Help

What size 12pt sockets do I need for the ARP LS2 head studs, standard kit? Is it 1/2" for the main head studs and 12mm for the top 5? Or is it just 1/2" for all the head studs?

Also, when removing the nuts, do the studs come out with them? If not, is there any torque specs I should check with the head studs in the block? I've never worked with head studs before...and I'm swapping gaskets on my ARP headed motor.

Thanks for the quick help!

The nuts come off by themselves. The stud itself sits in the block handtight then you slap the head on and torque the nuts down to 85lbs.

I dont remember the nut size off hand but I want to say 15mm and 12mm. Having an entire set of sockets is always a good idea though.
