Hi guys took my head off the other day and had to take cams out to get to the head bolts. just wondering if you can put the cams straight back in roughly how you took them out or if it needs putting in precisely in a certain way and a certain point. dont fancy putting the cams back in putting the engine back in the car and completely ruining the engine because the fuellings all messed up by dodgy cam set up lol any advice pwease
