Head bolts should be tightened to 58 ± 1 lb in sequence, backed off, tightened to 15 ± 1 ft-lb in sequence, then turned 90 deg in sequence then turned another 90 deg in sequence. This is only with stock head bolts as they are torque-to-yield. ARP studs should be tightened according to ARP's specs.
Camshaft sprocket bolts are tightened to 65 ± 7 ft-lbs.
The first numbers are metric units.
