rocker shafts installed backwards... long read. but pics!

I'll tell you this from DIRECT experience. IT MATTERS how the shafts are installed. Although yours are at least right side up, they're probably not hurt. BUT, years ago I was hurt on the job. At that same time I had to have an engine built. I always do my own, but then I had to hire a local "reputable" machine shop to build it. Just a mild 360 for a D100. They installed rocker shafts on both upside down and backwards. Also they just threw the rockers on randomly. Within 200 miles, the rockers and shafts were toast and squeaking and ticking like hell. With the oil holes pointing UP and not down, the rockers had no oil to ride on on the bottom where all the pressure is. Needless to say, I crossed that particular machine shop off my list.
