What I don't understand is that if these rules are meant to "reduce failures" then why they do not allow roller rockers or even pushrod guide plates. Neither will give a distinct performance improvement, but would reduce failures at one of the weakest points on a stocker engine. Both are legal per IHRA rules. This is assuming that this list of rule revisions is accurate and complete.
