you have long bolts and short bolts, long bolts go in positions 1,4,5,8,9 - short bolts remaining positions, all long bolts go in back of engine, toward fire wall or front of dash, those are positions starting at passenger side to drivers side, 8,4,1,5,9, so 1 is in the center position, 9 on drivers side. short bolts in front, positions passenger side 7, 3, 2, 6,10, stud is in position 10. Tighten bolts in sequence, starting at 1, long bolts get 32Nm, short bolts get 29Nm, next pass torque all to 58NM, than final pass add an angle of 100 degrees, little more than 1/4 turn with wrench. Bolts should have 11.9 on head, the tightening specification is called a torque plus angle to yield, that is why in your gasket kit is tells you to replace the bolts, it is recommended. I know, because I am the GM Manager for fastening engineering. Hope this helps
