Hughes Engines 1.6 Rocker Geometry/Setup

I've never understood why anyone would argue over getting something "right". Sure, these engines ran fifty plus years with the rocker shafts not in the optimized location, but if you're building one from the ground up, there's no reason not to make everything as right as it can be. You cannot argue what correct positioning of the rocker shaft and corrected geometry does for valve guide and stem wear, plus the reduction of friction can actually add up to some power gains......however small. It all adds up. There's just no reason not to get it dead right and it has nothing to do with being a guru, but more about being smart. I mean, it's not like it costs thousands of dollars to do.
