According to my manual the removal and the replacement sequence are different. Removal (looking from the cam sprockets )
headbolt 1-3-9-5-7 are on the left and 2-4-10-9-8 are on the right. Remove in that progression.
Instillation 9-5-1-3-7 are on the left and 10-6-2-4-8 are on the right tighten in that order.
Tighten to 25Nm or 18 ft/lb. and retighten the cyl hd blt 70 deg plus 70 deg plus 50 deg using the angular torque guage KM-470-B.
Hope this helps. Might help to make a sketch and label the 5 headbolts on each side.

Go to AutoZone website and create an account. The info for Chevy Aveo is pretty good, was my primary source, when doing an engine swap. They have free online manuals for many cars.

Will have a pic for head bolt removal/ installation as well as torque/ angle specs

I believe its different for diff years so be careful if you do it wrong you'll destroy the heads. You MUST use new head bolts for this procedure!!!Get the shop manual for your year and you won't go wrong plus you'll have tons of info for other issues.....

The GM torque guidelines are as follows for the 05 aveo. 18 foot pounds then 60 degrees then sixty degrees then sixty degrees then at last 10 degrees. I have seen all over the place missing that last 60 degrees. Its not a lot and maybe it will never give you issues. But this is from the GM specks at the dealership.

Does someone mind explaining the 60 degrees + 60 degrees + 10 degrees procedure?

So I tighten the bolts to 18 foot pounds each, in the sequence order provided. BUT then I make 60 degree turns on each bolt afterwards? or is it you turn each bolt 60 degrees at a time? I am a bit confused by this.
