lets think about this
the cam was designed to run on a l67 si was ground using l67 cam timing
that means that l67 stock chain and gears would place it at zero advance
ooooooor since your insistant on having someone give u an awnser get a degree wheel kid and dial indicator and find out for yourself witch one get u the installed icl you want then you can do everyone a great service and find out most definitively witch chain and gear set has more or less advance in it
my personal guess I neither are any different
the s1x cam having advance built in to it is pretty damn normal most cam manufacurers grind in 2-4* od advance to help midrange and low end power anyways
