If the cam chain is not connected you put the cams in their proper location as described by the marks, then make sure the crank is in the right position. The key is to ensure that there is no slack in the cam chain on the right side, the side toward the front of the engine. After its installed and you've released the cam chain tensioner, manually rotate the crankshaft clockwise 2 full turns and ensure that the cams return to the proper position when the T mark is properly aligned.
