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, just unbolt them.

 

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.

 

Cheers for that
top of your head do you know the bolt head size? is it 14mm?

 

The bolt size is actually 11mm but the head on the bolt requires a 14mm socket to remove them.
