Cam Rocker Ratio Choice

There is a thread on Yellow Bullet on this very subject. There are pros & cons, but with 600 lift, I think they are about equal. With very high lifts, the higher ratio allows for a larger cam barrel [ base circle ] which will resist deflection better & less loss of valve lift.
Also agree with Scamp's comments about high ratio rockers & the closeness of the adjuster/prod to the shaft. Would think that recessing an alum rocker for p/rod clearance would weaken it...
