I was just thinking of some of the cam only cars, and other big cam/heads cars turning 7K+ rpms. On the gen I motors they would general have rocker-stud girdles, but as I look around I can't find any information on these. As there doesn't seem to be an inbetween from stock type to the jessel style shaft mounted rockers. Anyone have some insight as to why?
