    Installing 1.6 roller rockers on a ZZ4

     



    I am told that 1.6 roller rockers will increase lift and HP and give this engine a lopier idle. Has anyone done this and have any advise, part numbers, etc? Thanks.

    it does increase lift & CAN in crease HP... its trial & error, some people use 1.6 on intake & exhause, some do it just on exhaust...or intake...depends what works.
    As I recall your ZZ4 uses self aligning rockers, so keep that in mind if buying rockers.John
