A little better...

Wonder if anyone has done a before/after roller rocker swap...

Not that I know of, the main reason I went to roller rockers was the valve guides. I was having issues wearing out valve guides from the stock scrub rocker setup, no more problems scince the roller rockers went on. Though I'd guess,and Randy @ Harland Sharp agreed after seeing the stockers, that there should be a decent gain considering the design of the stock rockers.
