imwith tom on this one... ive never seen the head studs pull out because of 15 measly psi on a 16G... ARP's are good for AT LEAST 220kpsi on the studs... there needs to be ALOT more than 15psi and knocking to stretch the studs or strip the threads on the deck.

if you want a cylinder head that is complete and never been cut, let me know. i have one in my garage. i would recommend using the 3rd gen HLA's regardless of any route you take.
