6 Pushrods come in many flavors, but for the most part you'll find the typical steel tube in 5/16-inch diameter with welded pivot ball ends, as these examples are seen here. They work fine for a stock engine, but like their sled rocker arm counterparts, are not the most accurate. They can flex enough with aftermarket springs/high lift cams to reduce the amount of true lift the valve sees. Plus they are not hardened to work with pushrod guideplates (the pushrod actually rubs/touches these plates to keep them in line with the valve it actuates). Finally, we've actually seen the pivot balls fail at the weld with aggressive cam profiles. View Related Article
