I wouldn't even think about changing rocker ratios without verifying piston to valve clearance.
I choose a camshaft that will give the lift as required, with a lower ratio rocker like 1.6, rather than run a low lift cam with 1.7s, 1.72s or 1.8s.
If you find benefit with high ratio rockers, you have the wrong camshaft.
