A----5----1----3----7
A----6----4----2----8
A= 8mm bolts (external Torx), the rest are 12mm bolts (internal Torx)
Install the 8 - 12mm bolts first and tighten to 24ft/lb, then install the 8mm bolts and tighten to 24 ft/lb, then go back and rotate the 12mm bolts an additional 90 degrees (the bolts are "torque-to-yield" bolts, discard the old ones and use new bolts for installation)
I would recommend that you consult a repair manual for torque values as well as tightening sequence
It is important to know the head bolt tightening sequence and the torque of a vehicle. For the Fiat Punto it is 20nm, 30nm, 90 degree turn, 90 degree turn, then in order 8,6,2,5,10,7,3,1,4,9.

Rover 20T2N 2.0Ltr Diesel engine Cam cover torques are listed as 12 Nm. No tightening sequence is listed .
always start in the middle and work outwards,, head stud torque is 115 then 145
Just criss-cross on the bolts and don't tighten them all in sequence, just like tightening lug nuts on a wheel.

get specs from your local librarys technical isle look up specs and tightening sequence.
The proper bolt tightening sequence for an 08 Dyna outer primary cover typically involves starting from the center and working your way outward in a crisscross pattern. This helps ensure even pressure across the cover. Begin by tightening the bolts to the specified torque in several steps, gradually increasing to the final torque specification recommended in the service manual. Always refer to the manufacturer's guidelines for the exact torque values and sequence.
