Well since no one will answer your question
Besides them being two different ratio's and brand.
The 1.8 ratio rocker arm will give you more lift meaning it will push your intake and exhaust valves further down than a 1.7 ratio rocker arm will.
So if you have changed your cam or have intalled milled heads they are saying you need to use the 1.7 ratio rocker arms to keep from having PTV issues.
The above was based on you saying my current set up which normally means you have done some kind of Modification to your engine.
Hope I have helped
