You need to buy a Nissan gasket set if possible, the head and intake gaskets are layered metal and there are o-rings involved, if you cannot find the info you need PM me and I will go thru it the best I can from my "model SD series diesel engine manual, it has everything including what to torque the head bolts to at every step and the order they are tightened.

When you remove your head you need to see where the o-rings go, take photos, also look between the intake and exhaust valve seats for cracks in the head.
