850 timing 1 tooth off

[Wyoben]

I will try to be brief and to the point,Doing timing belt on 94 850 turbo . I got the cam gears marked as close as possible to notches in upper cover, They are lined up as best as can be,but crank mark is still 1 tooth off .I replaced everything H2o pump, idler , tensioner , belt etc . It doesnt seem that anything moved when removing or installing all new parts .I'm wondering if I should pull pin on tensioner and turn crank by hand 2 revolutions and see if all is well , and if i can get crank mark dead on and re read to see if cam gears will line upbetter when crank mark is dead on etc ?
