Rocker Arm Set of 18, race prepped, stock style cast steel, Ford 289-351W (7/16 stud 1.6 ratio)

Cobra Automotive has a unique offering for the vintage racer competing under strict FIA rules requiring the use of OE type rocker arms.  We begin by hand selecting sets of stock style, cast steel rockers.  Next, we grind oil slots in the push rod cups, and then the rockers and balls are “lapped” for smooth operation.  Then the rockers and balls are machined for 7/16 studs.  Finally they are cryogenically treated for strength and durability.  Sold in sets of 18 so you automatically have 2 for spares.
