Here's the torque sequence for the 318 (5.2) intake manifold on the right, from a later model. It'll be the same.


And here is the torque sequence for the cylinder head. (the V-6 is shown also, pay no attention to it...it has two less bolts)

Can I such jest you buy all new head bolts. I rebuilt a Isuzu NPR couple years back when I was torquing the head, one broke on me. Lucky it broke above the block. So I had to remove the head buy new head gasket and replace all the bolts.

No need to replace the bolts on that engine ( the 318), just inspect them. On some engines you need to replace the bolts as they are not reusable, this is not one of those
