Big Block Timing Chain

[Ed51]

I need guidance here guys.I am assembling a 427 BBC after getting everything back from the machine shop. After sliding in the cam I went to put on the new CLOYES timing set. There are three keyways,and I want to put it in straight up.The marks are giving me pause,there were NO instructions in the box. There is a triangle,a square "O" and a round "O". Is the round "O' the one I need? :dunno :dunno :eek:

The triangle will advance the cam 2 dgs, the square will retard the cam 2 dgs, and the circle will place the cam straight up. :D
