NISSAN TIME CHAINS VK56DE 2004

Good friends, I am new in this forum, I will appreciate if you can help me with the time of a Nissan Pathfinder armed, V8, 5.6 L, 2004, VK56 engine.
Colatas changed for overheating, and the marks of the time we had done and exchanged camshafts were lost.
We do not know the position of the camshafts.
I will be very grateful if someone helps me.
THANK YOU
