Lift, duration and valve opening time are all there for each option.
Maybe this partially explains why theres no concrete info, in that at various points folk may have tried an 1.8NA cam and may or may not have had success with it, depending on exactly which option they choose. Given the wild differences i can imagine that each cam will perform differently. It also shows that simply saying "AGN" cam or "ADR" cam isnt enough, as both of those engines have multiple cam choices!
