This can easily be checked if you look into the ports, or just inspect the camshafts' position before you put the cover back on. To achieve this, the camshafts at the opposite banks must be off by 180 degrees, hence you turn the crank a complete revolution. It does not matter which bank you time first, the combustion will be determined by the camshaft position sensor.
Hi - do you know of a table showing the different valve positions in OT? I am suspecting that the replacement cylinder head which I got on eBay came with the wrong camshafts. I found a table (https://www.renntech.org/uploads/monthly_04_2014/post-93239-0-95551000-1397312927.png), but it is for a different engine. Thnx
