Ls2 timing

[geovair66]

Hey all, I have a 2001 sl2 dohc 1.9 that I took apart to put new rings in and replace two burnt exhaust valves. I can't find any info on timing of the two cam sprockets as to where they get positioned for timing. I found a 1999 video and it shows the sprocket timing holes that you put the pin or drill bits in the holes at about 7 o'clock going clockwise. I have holes at 6 oclock on my 2001. Did I miss them or are the line up holes in the 2001 different than the 1999? Thanks.
