cylinder head unbolting sequence?
I know there usually is a sequence for torqueing head bolts down but is there a sequence for unbolting them to remove the heads from the block.
Engine is a phase 1 with hydraulic tappets

No it’s best you should release the tension evenly going from opposite bolts ideally following the same pattern.
Turn each bolt half turn at a time and so on increasing the turns as the tension is released. Once the head is free then take the bolts out one by one.
