I'm trying to decide which rocker ratio to use for my new motor with E heads. Based on installed height and coil bind, I measured both, I have up to 0.638" lift with a distance of 0.060" from CB. If I use a 1.6 rocker I will have 0.640" lift but I have never run that close to CB before, has anyone run that close without issue? I know it is preferable to run closer rather than further from CB for spring control, but is 0.060", or 0.058" safe?
