It has been a long time since I have set valve timing on a Yblock.
 I am aware of counting the 12 pins on the chain to set the timing.  I set #1 valves to TDC and checked #6 at TDC. But having trouble setting the gears.  Are the cam and the crank keys ways set at the 3 clock position looking from the front of the engine?  Or is there another way to set the keyways on the cam and crank? 
Any help would be appreciated.  Thanks
