Looks like you are using an aftermarket gearset. There's a few things things to keep track of
Balancer and cam balancer gear must line up their dots.
Then, turn the cam so the key is approx 4-5 oclock
Turn crank so key is approx 2 oclock
If there's a dot or 0 on the key hole of the crank gear, put it on they keyway.
Now the 0 or dot on the tooth of the crank gear should be pointing to 12 oclock
Line up the cam gear dot/keyway and you should be able to take pics of all dots/0's lining up.
And put your old crank gear back on with the new one on. All dots should line up. This is your triple check that everything is correct.
