I have seen lower ratio rocker arms for sale, advertised for breaking in a flat tappet cams. Seems like they were 1.3:1 if memory serves me. From my perspective, swapping out the rockers would be a lot easier than swapping the valve spings, however the cost was significant. If you did a lot of engines it would pay to buy them, but not for a single build - my opinion only.
