ARP head studs questions

Does anyone know why these are shorter, and which head bolt holes they go into?
Also, it seems like other people on this forum have torqued the studs to 65 ft lbs with PN 234-4316. The instructions that came with mine in the ARP box say to torque the 7/16" diameter studs in 3 passes to 80 ft lbs. So which is correct?? It says the tensile strength is 200, 000 psi, if that helps.
Thanks for any help!
I thought this was the last piece of info I needed before starting to install my heads. Unfortunately I completely forgot to get deck to head dowel pins.
