1.7's will give you more lift. But NOT more duration.

Take the LOBE lift spec of the cam, multiply it by 1.6, that'll be your advertised lift with the 1.6 rockers. muliply lobe lift by 1.7, you guessed it, advertised lift with the 1.7's.

I have a set of 1.7's on my 347, and have had ZERO problems. Stud girdle might be a good idea though.
