I have reset the timing today. I have done following
1: lock engine at tdc, aligned camshafts with the camshaft lockingblocks
2: unlock everything, spin crankshaft with a ratchet 1 full turn so that the marks on camshafts face up again, re-check camshaft positioning, adjust what is out of time.
3. Rotated the engine once more, this time all camshafts aligned perfectly! intake cams on both banks are fully retarded to the left when i check the realigment.
4. When i released the chaintensioner to put the upper covers on, i noticed there was some slack between bank 1 and 2 cam sprockets (around the U-guide) that goes away if i gently pry the tensioner guide piece, is that the way it supposed to be? I have put the valve covers on and soon be ready for startup again 😄
