Use for applications for heads which accept 7/16" screw in studs.

Great for factory or aftermarket heads which use screw in studs and guide plates.

NOTE- Most 351c and Big Block Ford heads use pedestal mount rockers. Pedestal mount rockers use a small 5/16" bolt to hold the rockers down and are not adjustable.

Pedestal mount heads require machine work to use screw in studs like these. It's the buyers responsibility to verify their heads will accept this type of stud before purchase.

Those interested in roller rockers which bolt directly onto stock pedestal mount heads can write about other options. We carry "Yella Terra" rockers which fit all those pedestal mount heads without machining. Send us a message.
