Head bolts

Whats the exact torque for the head bolts and the bolts for the intake mainfold. I would love to get it in Nm and not ft/lbs because we use the metric system.

Cant help you on the metric stuff, but we always go 65 ft/lbs for head bolts, in a 2 step increment. For intake bolts its only like 12-20lbs. I usually just do it without a torque wrench. Just make sure that you dont radically overtighten any. And make sure you follow the proper crossing sequence on the intake, and the proper order for the heads too.

ft lbs * 1.356 = nm

head bolts- 65ft lbs=88 nm

intake- 30 ft lbs=40nm
