Missing holes in head gasket?

[old-and-rusty]

Hiya,
According to the bible :
1). First tighten all bolts to 29 Nm (22 ft-lbs).
2). Then tighten all bolts to 78 Nm (58 ft-lbs).
3). Loosen all bolts completely.
4). Re-tighten all bolts to 29 Nm (22 ft-lbs).
5). Re-tighten all bolts to 74 to 83 Nm (54 to 61 ft-lbs), or with an angle wrench turn all bolts 90 to 95 degrees clockwise.

That does sound a bit vague for the final tightening though and there`s no mention of having to re-torque the bolts after running the engine.

Hope this helps anyway .
Regards,
Ian.
