W speed Patrol head bolt tightening pattern

In what order do you tighten the head bolts and to what torque? Same engine as WC.

Thanks,

WC/WD/W Speed patrol all used the same engine. 1/2 inch studs tighten to 70ft/lbs and the 3/8 to 25ft/lbs. As for a pattern you start in the center and work your way out using an X pattern till you get all them done. I do like 25 then 40 then 60 then 70 so as to keep things even across the head at all times. Then once warm re-torque them. Spec come from the I-T manual
