What is the difference between ARP2000, L19 and CA625+?
ARP2000 suits most high-performance builds. L19 offers higher strength but is sensitive to handling and corrosion. CA625+ is used for extreme cylinder pressure or rpm.
Why is ARP lubricant important?
ARP torque values assume Ultra-Torque lubricant on threads and under the head. Without it, clamp load becomes unpredictable.
What are the torque specifications for the ARP VR38 Head Stud Kit?
For the ARP VR38 Head Stud Kit, follow ARP's recommended torque specifications. Typically, you should torque the studs to around 80 ft-lb using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate guidance.
Do I need to machine the cylinder head for the ARP VR38 Head Studs?
Generally, the ARP VR38 Head Studs should fit without additional machining. However, it's crucial to ensure that the cylinder head and block surfaces are flat and within OEM specifications to achieve proper sealing and torque accuracy.
Can the ARP VR38 Head Stud Kit be reused after removal?
ARP recommends that head studs be replaced after removal, especially if they have been torqued to yield. While the ARP 2000 material is durable, it's best practice to use new studs to ensure reliability and performance in high-stress applications.
What is the benefit of using hardened parallel washers with the ARP VR38 Head Stud Kit?
The hardened parallel washers included with the ARP VR38 Head Stud Kit help distribute the load evenly across the cylinder head. This prevents distortion and ensures accurate torque readings, which is critical for maintaining head gasket integrity under high-performance conditions.
Is the ARP VR38 Head Stud Kit suitable for high boost applications?
Yes, the ARP VR38 Head Stud Kit is designed to handle high boost applications due to its superior tensile strength of 220,000 psi. However, the overall reliability will also depend on proper machining, clearances, tuning, and fuel quality.
