Understood, basically I have looked at all my motors and when I look at the cam gear with the piston at TDC the cam gear is just past 12 o'clock on the motors from the factory. As such I just make sure to place it in the same position when I reassemble the motor. Either way as Union stated, it is very important to check the valve adjustment when ever you have the crank or cam gear out for servicing upon reassembly.
