Chevy Small Block - Secrets Of The Cheap Hydraulic Roller Lifters
All Ford hydraulic roller cam motors use a net valve lash system for the rocker arms. When moving up to a performance roller cam, you should spend the money to have the stock heads machined for screw-in studs and guideplates so you can use an adjustable valvetrain and roller rockers. These stock iron heads now sport Crane 31/48-inch screw-in studs, guideplates, hardened pushrods, and Energizer 1.6:1 roller rockers. Slover's Porting Service did the work for us on these heads.
