im not that sure is there a big difference?

a little bit...if you look i know the 1.6s that i bought had1.6 stamped on with some other bs...but the 1.7 would create a higher lift that could help you a little more on the top end if the motor is set up for them

the ratio should be stamped on them.

even if you have the 1.6 you can still pick up a couple of hp by putting them on because they create less friction then the stock rocker arms

+1 on the HP from less friction. Its not gonna be a huge amount, but every little bit adds up.
