These 9/16" to 1/2" Ford 4.6L, 5.4L, 5.8L and 5.0 Coyote custom head studs were originally designed for use in Top Fuel. They are much larger than the commonly used 11mm head studs and requires the block to be tapped to 9/16-12.
Torque can be increased up to 125 ft lbs. Cylinder honing required after installation with torque plates. Some cylinder heads will require stud holes to be reamed to accommodate larger 1/2" stud. May require shorter dowel pins.
Includes 20 studs, 20 nuts and 20 hard washers. Not recommended on iron blocks.
