when setting cams at TDC do the pr3's or the "UP" arrows line up in the middle?

 

UP arrows

 

well technically they are up, but not straight up. if you notice on the back of the cam gear there are two lines in the middle. you need to look real close for this. these lines need to be flush with the head. the two inner lines on the back of the gears need to line up. hope this helps, its kinda confusing.
