Eliminate Blown Head Gaskets
ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. Unlike many fasteners, they are heat-treated prior to thread rolling and machining. This ensures maximum clamp loads can be achieved and maintained without damaging the threads. Racers have relied on ARP head studs for maximum durability since the 1960's.

12-Point Fasteners
ARP Pro Series kits feature compact 12-point nuts for maximum valvetrain clearance. These Mustang head stud kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.

Fits
1982-1995 Mustang 5.0 V8 with OEM heads or use 1/2" to 7/16" bushings to fit aftermarket heads
