Since stud mounted rockers are required, is the head going to be rigid enough to use without a stud girdle... or is a stud girdle going to have to be used on solid roller high spring pressure applications?
We use stud mount rockers on BBC engines with 850 hp, and 600 hp sbc's without girdles. Rocker arm issues really aren't something we see at all. If someone wants to add girdles, no problem, but we rarely see anyone use them on ours.
