After consulting a buddy in the tool and die shop, doing some measuring and looking at a conversion chart, here's what we came up with. The next larger size to 8mm that would cut threads and not enlarge the bolthole would be a 3/8 SAE. In fact all I had to do was cut the threads without even drilling the head. What follows are the highlight pics of the whole affair. First the rocker assembly with the bolt passage enlarged for the 3/8 bolt. The bolt on the right is the original showing the pulled out threads. The other bolt is a 3/8 hexhead capscrew with the shank milled down to 7mm to allow oil to pass to the rocker shaft.
