do you know what the difference is in the cams, as in lift and duration?

SiR1 and SiR2 are trim levels and do not designate different engine generations.

you can only base by year with g1 = 89-91, g2 = 92-95, g3 = 96-00

g2 and above had 10.4:1 CR vs the 10.2:1 of the g1 and usdm b16a
g1 had 160hp just like the us models, and g2 and above had 170hp.
