Anyone use 1.7 ratio rocker arms???

Plus, higher ratio rockers create two new problems:
- stronger springs reqd to control the valvetrain
- stronger prods that will not flex with the stronger springs. Bigger diam is stronger/better v same diam with thicker wall, but could be a nightmare to set up, as in the above post.

Agree with RRR. 1.7 rockers would add about 3-4*@ 050 of effective duration, so have a cam ground accordingly for use with 1.5 rockers.
