Am i checking the timing wrong?

Yes, you did the timing check wrong. You need the IN and EX lines flat with the top of the head when you do that. You want the chain tight between the two cam sprockets. Also, the crank needs to be on the TDC mark for cylinder 2.

When you put it back together after you fix the CCT, just remember to spin the crank two full turns by hand to make sure its not hitting anything hard. That way, even if the timing is off by a tooth, it wont hurt anything to try to run it that way. That's just a sanity check.
