some times when you pull the pin on the tensioner it pulls one of the cams off the timing mark.
remove the cam covers and compare the timing marks to double check that the HASH marks all line up. you can not check the crank timing mark with the cover or the pulley in place. but as long as you used the HASH mark on the REAR if the crank sprocket and not any of the marks on the front face of the crank sprocket, it should be ok.
if you are not 200% sure about the crank, you can remove the crank bolt and feel for the ''key way''. it should be in the 6 oclock position when lined up correctly.
