Hi! you have some many details to know.
Fisrt of all you need an specific tool to adjust number 1 and 9 bolts.
The sequence of torque you can see it on google images searching EA81 Head Torque, you will find the sequence there.
The torque you must apply is 22 ft-lb then 43ft-lb and finally 47 ft-lb, don´t need to use any sealant and you do not need to remove the cam towers because thats bolts (#4 and 5) also adjust the head.
Finally 6 mm bolts need 8 ft-lb torque, and you hae to torque thats bolts after all the head torque
Drive the car for at least 1000 km and then, with the engine cold, retorque to 47ft-lb-
