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 is the recommended torque specification for the ARP Custom Age 625+ head studs on a 1JZ or 2JZ engine?
For the ARP Custom Age 625+ head studs, you should follow ARP's guidelines for torque specifications. Typically, the recommended torque is around 80 ft-lb when using ARP Ultra-Torque lubricant. Always verify with the latest ARP instructions for the most accurate specifications.
Do I need to machine the cylinder head when installing ARP Custom Age 625+ head studs?
While the ARP Custom Age 625+ head studs are designed for a direct fit, it's advisable to ensure the cylinder head and block surfaces are properly machined and flat. This ensures optimal sealing and performance. Always check for warpage before installation.
Can I reuse the ARP Custom Age 625+ head studs after removing them?
Yes, the ARP Custom Age 625+ head studs are reusable, provided they have not been damaged or stretched beyond their limits. Always inspect the studs for any signs of wear or deformation before reinstallation.
What additional components should I consider when upgrading to ARP Custom Age 625+ head studs?
When upgrading to ARP Custom Age 625+ head studs, consider also using a high-quality head gasket and ensuring that your cylinder head is properly torqued down. Additionally, check that your engine's cooling system is capable of handling any increased performance demands.
