1.6 or 1.7 rocker arms?

[juiceman]

just out of couriousity whats the difference between 1.6 and 1.7 rockers other than the lift ratio? they're band aids? for what? and low duration doesnt exactly make more power but motorsport cams have high duration to begin with so going with a bigger cam will cause you to lose power due to excessive duration( which does what people?) so if you want more lift but need to keep the cam you have then use 1.7's. but, im sure for your motor 1.6's will be good.
