FAQ
Do I need to replace both heads?
Not always, but we recommend inspecting both banks. Many customers replace in pairs to minimize downtime.
Are these heads compatible with ARP studs?
Yes. These heads work with OEM bolts or ARP studs when installed per torque specs.
Do these include valves and springs?
Valve components are included per Industrial Injection’s standard reman spec. If you’re building for higher power, consider upgraded springs and retainers.
Is tuning required after installation?
No tuning is required for stock-reman heads. Verify injector balance rates and clear any stored codes after reassembly.
