The chains would be the two, one in each head that connect the cams. Even before you remove the engine set it to TDC. These engines are different from those you may have worked on in the past, and setting it to TDC resolves lots of maintenance disassembly issues. This must be done before removing the valve covers as the valve covers also restrain the cams. If the engine is out you really should consider the IMS bearing. If you are going to replace the cam chains in the heads the IMS bearing is not much more work and you are already locked at TDC. You'll kick yourself if you don't change that bearing when you have the chance. Replace the chain guides for sure if you are going this far. You also need to check the dual mass flywheel. All this is part of the fun and games of working on your own 986.
