There are two chains. Are you replacing both heads or only one? If it is on the left side, the right needs to be removed first. If it is the right side, only the right needs removed.
Regardless, I attached all timing chain and component info below for you. If you need anything with the cylinder head such as torque specifications, let me know.
Let me know if this helps or if you have other questions.
See pics below and let me know if that is what you needed. As far as timing marks, you will be focusing on colored links on the chain and positioning.
