I am aware and have heard of SR heads needing a little bulking up for higher rpm rage... of course I am an idiot you are thinking, but any suggestions on parts such as rocker arm stoppers. What will these benefit me? Thanks, Matt

keeps you from fucking up ur valves if you mis-shift at a high RPM. Id say rocker up stoppers, some valve springs and some retainers. Since your swapping valve springs, have em check the vlave guides and swap in some fresh ones if they're chewed up.
