ARP Cylinder Head Stud Kit for Ford 2300cc Pinto 1974-1980
ARP 151-4202 cylinder head stud kit delivers precise clamping for Ford 2.3L Pinto engines in vehicles like 1974-1980 Pinto, 1974-1978 Mustang II, and 1975-1980 Mercury Bobcat. These studs use 8740 chrome moly alloy heat-treated to 190,000 PSI for consistent performance under extreme loads. Thread rolling after heat treatment boosts fatigue strength by 2000% over pre-heat methods used by others.
Key Features
- 8740 Chrome Moly Material: Heat-treated to 190,000 PSI tensile strength ensures reliable head sealing in competition builds
- Centerless Ground: Provides concentric precision so heads and gaskets align perfectly without binding
- Post-Heat Thread Rolling: Increases fatigue resistance 2000% for longer life in high-stress racing applications
- Undercut Studs: Equalizes stretch on shorter studs for uniform clamping force and gasket compression control
- Black Oxide Finish, USA Made: Resists corrosion with ARP quality stamp on every stud
Product Notes

ARP
ARP (Automotive Racing Products) is the world’s premier manufacturer of high-strength engine and driveline fasteners—head studs and bolts, main studs, rod bolts, and more—engineered and manufactured in-house from start to finish for race-proven reliability. With vertically integrated processes that include cold heading, machining, heat-treating, thread rolling after heat treat, and rigorous QA, ARP maintains aerospace-level certifications (ISO 9001 and AS9100) and validates every part for repeatable clamp load and fatigue resistance. Signature alloys such as 8740 chromoly, ARP2000, L19, and Custom Age 625+ deliver ultimate tensile strengths up to the super-alloy range, while ARP Ultra-Torque fastener assembly lubricant helps achieve consistent pre-load during installation. From street performance builds to professional motorsport programs, ARP fasteners provide precise fitment, superior metallurgy, and the durability needed to keep engines together at elevated cylinder pressures and...

ARP Head Studs
ARP head studs replace factory head bolts with precision-machined threaded studs that provide more consistent and repeatable clamping force on the cylinder head gasket. Unlike head bolts that apply torque through both rotational and tensile forces, head studs allow the nut to be torqued concentrically on a stud that is already stationary, producing more even clamping load across the entire head gasket surface. Popular ARP Head Stud Applications ARP head studs are available for a wide range of performance and turbocharged engines including the Subaru EJ series, Honda K series and B series, Mitsubishi 4G63 and 4B11, Honda Civic and Integra, Toyota 2JZ-GTE, Nissan SR20DET and RB series, GM LS series, Ford Coyote and 5.0, and Dodge/Chrysler HEMI applications. ARP offers both 8740 chromoly and ARP2000 alloy head stud kits, with the ARP2000 material providing approximately 20 percent higher tensile strength for high-boost applications above 30 psi. Why are head studs preferred over head b...
