Prior to tightening the head, I spoke with ARP, and,I did the following :
Chased the holes using a 12x1.25 tap, using "Ultra Torque" lubricant, I hand tightened the studs,using 3 steps I tightened the studs in the correct sequence to 30,60,and then 90 ft lbs.
"Ultra Torque " went on stud threads, washers, and nuts.
I used Mitsu gasket.
