I would say remove the tensioners. Would make it easier just compress the timing chain tensioner and put a paper clip into the hole in the tensioner to hold the piston down. After that then removal is easy just make sure you have the timing marks lined up before you install the tensioners and i would say a tooth over to the right on the right bank and left on left bank due to when tensioner pops up to tension chains it compensates for the bit it will move it for. Thats how i did it however wait for more responses to get more and possibly better ideas on how to since its kinda hard for me to exactly say how i did it by words im more a hands on type
