I ran the break in with factory hyd rocker arms & pushrods while waiting on these, they come from Doug at Precision Oil Pumps in Clovis, CA. Stands, arms, spacers & r/a studs all came from Doug.. These arms require a ball/ball pushrod w/5/16" balls, they measure 9.256" o/all length (same as a BBC). A really nice package.
