Taurus -97 cylinderhead gaskets and bolts.

Hello from Finland.

I have Taurus -97 with blown head gasket and starting to fix it.
Problem is, i cant find any info how to tighten cylinderhead bolts.
My friend is on his way to Miami and i asked him to buy gasket set to me, because here it is expensive. (250+150 dollars for the bolts)
Is there only one option of gaskets for this car year -97?
It is 3.0 litres 12 valve engine.

Thanks for advance.

ps. sorry for my bad typing, english is not my first language...
