All of the head bolt holes are blind, but they must be cleaned properly. The factory head bolts have some very stiff thread locker on them.
The head bolt holes are tapped M11 x 2.0 for the large holes and M8 x 1.25 for the small ones.
Use the torque specs provided by ARP. I don't have the torque sequence in front of me, but I'm sure it's been posted here a thousand times. Try a search on head torque.
